No full textDimethyl(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)zinc(II)
No full textThe title compound, [Zn(CH3)2(C15H11N3)], was synthesized by the addition of dimethylzinc to 2,2′:6′,2′′-terpyridine and was crystallized by the slow evaporation of THF. The pentacoordinate ZnII atom, lying on a twofold rotation axis, displays a distorted trigonal-bipyramidal geometry, with two terminal N atoms at the axial positions and the central N atom and two methyl C atoms at the equatorial positions
[(4R,5R)-(2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(diphenylmethanolato)-κ2O:O′]bis(N-methylmethanaminato)titanium(IV)
No full textIn the title four-coordinate complex, [Ti(C2H6N)2(C31H28O4)], two symmetry-independent molecules are present in the asymmetric unit. The TiIV atom displays a distorted tetrahedral geometry, with Ti—O bond lengths ranging from 1.805 (3) to 1.830 (3) Å and O—Ti—O ligand bite angles of 100.16 (12) and 101.36 (12)°. The short Ti—N bond distances, ranging from 1.877 (4) to 1.905 (4) Å, indicate strong bonding between the TiIV atom and the dimethylamide ligands
Crystallographic and spectroscopic characterization of 5-chloropyridine-2,3-diamine
No full textThe two ortho-amino groups of the title compound, C5H6ClN3, twist out of the plane of the molecule to minimize intramolecular interaction between the amino hydrogen atoms. In the crystal, the amino groups and the pyridine N atom engage in intermolecular hydrogen bonding. The molecules pack into spiral hydrogen-bonded columns with offset face-to-face π-stacking.</jats:p
