Structure, magnetism and reactivity of a {MnIII(μ-O)2MnIV}3+ core towards oxidation of phenols
No full textNeutral, Cationic, and Anionic Low-Spin Iron(III) Complexes Stabilized by Amidophenolate and Iminobenzosemiquinonate Radical in N,N,O Ligands
No full textA brownish-black complex [Fe-III(L)(2)] (1) (S = 0), supported by two tridentate redox-active azo-appended o-amidophenolates [H2L = 2-(2-phenylazo)-anilino-4,6-di-tert-butylphenol], has been synthesized and structurally characterized. In CH2Cl2 1 displays two oxidative and two reductive 1e(-) redox processes at E-1/2 values of 0.48 and 1.06 V and -0.42 and -1.48 V vs SCE, respectively. The one-electron oxidized form [1](+) isolated as a green solid [Fe-III(L)(2)][BF4] (2) (S = 1/2) has been structurally characterized. Isolation of a dark ink-blue one-electron reduced form [1](-) has also been achieved [Co-III(eta(5)-C10H15)(2)][Fe-III(L)(2)] (3) (S = 1/2). Mossbauer spectral parameters unequivocally establish that 1 is a low-spin (LS) Fe-III complex. Careful analysis of Mossbauer spectral data of 2 and 3 at 200 and 80 K reveal that each complex has a major LS Fe-III and a minor LS Fe-II component (redox isomers): [Fe-III{(L-ISQ)(-center dot)}(2)](+) and [Fe-II{(L-IBQ)(0)}{(L-ISQ)(-center dot)}](+) (2) and [Fe-III{(L-AP)(2-)}(2)](-) and [Fe-II{(L-ISQ)(-center dot)}{(L-AP)(2-)}](-) (3). Notably, for both at 8 K mainly the major component exists. Broken-Symmetry (BS) Density Functional Theory (DFT) calculations at the B3LYP level reveals that in 1 the unpaired electron of LS Fe-III is strongly antiferromagnetically coupled with a pi-radical of o-iminobenzosemiquinonate(1-) (L-ISQ)(-center dot) form of the ligand, delocalized over two ligands providing 3- charge (X-ray structure). DFT calculations reveal that the unpaired electron in 2 is due to (L-ISQ)(-center dot) [LS Fe-III (S-Fe = 1/2) is strongly coupled to one of the (L-ISQ)(-center dot) radicals (S-rad = 1/2)] and 3 is primarily a LS Fe-III complex, supported by two o-amidophenolate(2-) ligands. Time-Dependent-DFT calculations shed light on the origin of UV-vis-NIR spectral absorptions for 1-3. The collective consideration of Mossbauer, variable-temperature (77-298 K) electron paramagnetic resonance (EPR), and absorption spectral behavior at 298 K, and DFT results reveals that in 2 and 3 the valence-tautomerism is operative in the temperature range 80-300 K
Confluence of Minds: The Rabindranath Tagore and Patrick Geddes Reader on Education and Environment
No full textThis collection of seminal correspondences between Indian Nobel Laureate Rabindranath Tagore and Scottish polymath Robert Geddes are testimony to a great friendship and an even greater marriage between Eastern and Western schools of thought. This compilation uncovers a confluence of ideas on the environment, science, rural reconstruction and a holistic approach to education that resonates with the lived experiences of its students
Tagore's legacy for inclusive education, ecological awareness & intercultural understanding
No full textRabindranath Tagore was an ‘organic intellectual’ (Gramsci 1971), whose thoughts and work still intrigues many because of his unique ability to find synthesis between supposedly contradictory ideas. Though he is more well-known as a mystical poet, he spent much of his life-time, energy and material resources to build a school and a University for rural reconstruction, environmental sustainability, as well as international intercultural understandin

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
