title: Tris[2-(1,3-thiazol-2-yl-κN)-1H-benzimidazole-κN3]zinc(II) dinitrate ethanol hemisolvate monohydrate at 100 K.
abstract: The Zn(II) center in the dicationic complex of the title compound, [Zn(C(10)H(7)N(3)S)(3)](NO(3))(2)·0.5C(2)H(5)OH·H(2)O, is in a distorted octahedral environment with imperfect noncrystallographic C(3) 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 π-stacking is observed between one type of symmetry-related benzene rings.
