Tris[2-(1,3-thia­zol-2-yl-[kappa]N)-1H-benz­imidazole-[kappa]N3]zinc(II) dinitrate ethanol hemisolvate monohydrate at 100 K

Abstract: The ZnII center in the dicationic complex of the title com­pound, [Zn(C10H7N3S)3](NO3)2·0.5C2H5OH·H2O, is in a dis­torted octa­hedral environment with imperfect noncrystallographic C3 symmetry. Each 2-(1,3-thia­zol-2-yl)-1H-benz­imidazole ligand coordinates in a bidentate manner, with the Zn-N(imidazole) bond lengths approximately 0.14 Å shorter than the Zn-N(thia­zole) bond lengths. Charge-assisted hydrogen bonds connect cations, anions and water mol­ecules. A lattice void is occupied by an ethanol solvent mol­ecule disordered about a crystallographic inversion center and [pi]-stacking is observed between one type of symmetry-related benzene rings.

Formula: [Zn(C10H7N3S)3](NO3)2·0.5C2H6O·H2O
