N-(naphthyl)-N′-(methoxy carbonyl)thiocarbamide and its Cu(I) complex: synthesis, spectroscopic, X-ray, DFT andin vitrocytotoxicity study
No full textThe structural characterization of two new compounds N-naphthyl-N′-methoxycarbonyl thiocarbamide (NMCT) (1) and its Cu(I) complex, bis(N-naphthyl-N′-methoxycarbonyl thiocarbamide) copper(I) chloride [(NMCT)2CuCl] (1a) have been done by spectroscopic techniques (FT-IR, 1H NMR, 13C NMR and electronic spectroscopy) and X-ray crystallography. To get a deeper insight of vibrational frequencies and electronic transitions, DFT and TD-DFT studies have also been performed. X-ray study revealed trigonal planar geometry around copper(I). The ligand coordinates through thione sulfur only. The cytotoxicity of 1 and 1a has been assayed in five human carcinoma cell lines, 2008, C13* (cervical carcinoma), A2780, A2780/CP and IGROV-1 (ovarian carcinoma). Both the compounds exhibited cytotoxicity. The inhibitory activity of copper complex was better than ligand against all the cell lines
Industrial arts curriculum project for the Thomas Butcher Children's School of Kansas Teachers College, Emporia, Kansas
No full textThis study was concerned with developing an innovative program for the Thomas Butcher Children's School of Kansas State Teachers College, Emporia, Kansas.A survey was made of the known innovative programs, with an in-depth comparison of similarities and dissimilarities of the three most notorious programs: The Industrial Arts Curriculum Project, The American Industries Project, and The Maryland Plan, and of the three most recent books directed toward elementary industrial arts: Teaching Elementary Industrial Art, Teaching Children About Technology, and Elementary School Industrial Arts, relative to rationale, objectives, and structure.The suggested program began with a definition of Industrial Arts for elementary education, followed by the rationale, objectives and structure. Communications was to receive the major emphasis at the Kindergarten level; transportation at the first grade level; shelter at the second grade level; clothing at the third and fourth grade level; and foods at the fifth and sixth grade level, although each could not be limited to any one grade level. Units under each category were followed by room preparation, minimal tool list, and material media suggestions.Thesis (Ed. S.
Chiral tricyclic triazolooxazine derived mesoionic carbene (MIC)-Pd(II) complexes of cyclohexene oxide scaffold: Synthesis, structure, and characterizations
No full textWe herein report the well-defined two novel chiral palladium(II) complexes 1(b−c), of the chiral N-fused tricyclic triazolooxazine derived mesoionic carbene (tz-MIC) ligand 1a. The chiral tricyclic PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) namely, trans-[tz-MIC)-PdI2(pyridine)] (1b), and the chiral tricyclic bis(tz-MIC)-palladium complex namely, cis-[tz-MIC)2-PdCl2] (1c). The chiral tricyclic trans-[tz-MIC)-PdI2(pyridine)] PEPPSI type complex (pyridine enhanced pre-catalyst preparation stabilization and initiation) (1b) was directly obtained from their respective chiral tricyclic triazolooxazinium iodide salt (1a), by treatment with PdCl2 and K2CO3 in pyridine in 77% yield. The chiral tricyclic triazolooxazinium iodide salt (1a), was first converted to its in-situ silver analogue by reaction with Ag2O and then subsequently upon treatment with (COD)PdCl2 to produce the chiral tricyclic (tz-MIC)2PdCl2 type palladium complex (1c) in 84% yield. All these palladium complexes were isolated for the first time and structurally characterized by 1H NMR and 13C{1H}-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis and single crystal X-ray crystallography.MKG thanks to the Council of Scientific and Industrial Research (CSIR File No: 09/087(0663)/2010-EMR-I), New Delhi, for financial support of this research.

Axially chiral bis-1,2,3-Triazol-4-ylidene–Ag(I)-MIC and, bis-Au(I)-MIC complexes of (R)-BINOL and (-)-Menthol scaffold: Synthesis, structure, and characterizations
No full textHerein, we report the novel axially chiral bis-Ag(I)-MIC and, bis-Au(I)-MIC complexes bearing axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands were synthesized. The enantiopure R-BINOL was employed as a basic unit to synthesize a axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1–2)a. In particular, the axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1–2)a, were obtained from the reaction of corresponding bis-1,2,3-triazole ligand precursor with methyl and ethyl iodide in 82−90% yields. Novel axially chiral bis-Ag(I)-MIC complexes (1 − 2)b, were prepared by the treatment of corresponding axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) iodide salts, (1 − 2)a, with Ag2O via in-situ deprotonation method in 69−86% yields. Novel axially chiral bis-Au(I)-MIC complex-2c was synthesized from their respective novel axially chiral bis-Ag(I)-MIC complex-2b, using transmetallation reaction with (SMe2)AuCl in 70% yield. All these novel axially chiral bis-Ag(I)-MIC and bis-Au(I)-MIC complexes were isolated for the first time and structurally characterized by 1H NMR and 13C{1H}-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis, specific optical rotation and, single crystal X-ray crystallography.MKG thanks to the Council of Scientific and Industrial Research (CSIR File No: 09/087(0663)/2010-EMR-I), New Delhi, for financial support of this research.

A unique supramolecular structure of poly [mu-oxo- bis(1,1,2,3,4,5-hexahydro-1-nitratotellurophene)] [(C4H8TeNO3)(2)O](n) with ---O-Te-O-Te-O-- cross linked chains
No full textPoly [mu-oxo bis(1,1,2,3,4,5-hexahydro-1-nitratotellurophene)] I, is prepared by the room temperature reaction of 1,1,2,3,4,5-hexahydro-1,1-diiadotellurophene with silver nitrate in deionised water. Crystals of 1 are monoclinic, space group C2/c with a=13.930(2) Angstrom, b =11.665(2) Angstrom, c=10.0682(11) Angstrom, beta=116.264(8)(0) and Z=4. The monomeric unit of the title compound is centrosymmetric, with an angular TeOTe skeleton containing bridging O atom at the centre of symmetry. These monomeric units are linked together through ---O-Te- O-Te -O--- cross linked chains and the nitrate groups are asymmetrically bidentate with a primary Te-ONO2 and a secondary Te---O semibonding interaction. Each nitrate group further participates in another Te---O semibonding interaction forming another asymmetric Te(NO3)(2)Te bridge. The structural characteristics of I are compared with related complexes
Crystal structure of [Fe(L<sup>1</sup>)<sub>2</sub>](ClO<sub>4</sub>)<sub>2</sub>.H<sub>2</sub>O having Fe<sup>II</sup>N<sub>6</sub> coordination [L<sup>1</sup>= 2,6- bis(pyrazol-1-ylmethyl)pyridine]
No full text973-975The structure
of the compound [Fe(L1)2](ClO4)2.H2O
(1)[L1= 2,6-
bis(pyrazol-1-ylmethyl)pyridine]
has been determined by X-ray crystallography at ≈130 K. Temperature-dependent magnetic
susceptibility and Mossbauer spectral studies reveal that the iron atom in 1 is
in the high-spin state at room temperature and in the low-spin state at low
temperature, whereas in [Fe(L2)2](ClO4)2.H2O
(2) and [Fe(L3)2](ClO4)2.H2O
(3) [L2 = 2,6-bis(3,5-
dimethylpyrazole-1-ylmethyl)pyridine
and L3 = 2-(pyrazol-1-ylmethyl)-
6-(3,5-dimethylpyrazol-1-ylmethyl)pyridine)
the iron atom is in the high-spin state at both the temperatures [Mahapatra S,
Mukherjee R, Polyhedron 12 (1993) 1603]. The metal-ligand bond distances
in 1 have been compared with those of 3, determined at ≈173 K
[Mahapatra S, Butcher R J, Mukherjee, R,
J chem Soc,
Dalton Trans (1993)
3723]. The Fe-Npyridine and Fe-Npyrazole
bond
distances in 1 are shorter by ~0.23 Å and ~0.14 Å,respectively, than
those for the high-spin complex 3, revealing its low-spin character. Moreover,
a noticeable variation of the N-Fe-N angles, leading to a more regular shape of
the FeIIN6 octahedron in 1, is observed
Pseudohalide-Controlled Assemblies of Copper-Schiff Base Complexes with an Encapsulated Sodium Ion: Synthesis, Crystal Structure, and Computational Studies
No full textThree new hetero-bimetallic coordination complexes [Na-(CuIIL1)2](ClO4)·0.5H2O (1), [Na(CuIIL2)2][CuI2(μ1,3-NCS)3]n
(2), and {[Na(CuIIL3)2](μ1,5-dca)}n (3; dca = dicyanamide) have been synthesized by using different Schiff base ligands [e.g., L1H2 = N,N=-bis(3-methoxysalicylidenimino)-1,3-diaminopentane, L2H2 = N,N=-bis(3-ethoxysalicylidenimino)- 1,3-diaminopropane, and L3H2 = N,N=-bis(5-bromo-3-methoxysalicylidenimino)-1,3-diaminopropane] in the presence
of pseudohalide coligands N3–, SCN–, and N(CN)2– (dca),respectively. The ligands and the complexes have been characterized
by microanalytical and spectroscopic techniques. The structures of the complexes, determined by single-crystal X-ray diffraction studies, show that in all cases a trinu-clear Na(CuIIL)2 unit is formed, but of different configurations. 1 does not include N3– anions. In contrast, in 2, SCN– extrudes partial in situ reduction of CuII to lead to the formation of an infinite [CuI
2(μ1,3-NCS)3]n anionic chain; and in 3, N(CN)2– bridges the metal–ligand assemblies to form a 1D polymeric chain. ESI-MS, UV/Vis spectroscopy, and cyclic voltammetry were performed to investigate the solution-state behavior of the complexes. Theoretical calculations of the optimized geometries of the complexes were carried out at the BLYP/DNP level to determine their relative stabilities from the HOMO–LUMO gap and chemical softness values
