Dichlorobis(2,2'-diamino-4,4'-bi-1,3-thiazole-²N,N')nickel(II) dihydrate

J.-G. Liu and D.-J. Xu

Abstract: The Ni^II atom in the crystal structure of the title compound, [NiCl₂(C₆H₆N₄S₂)₂]·2H₂O, has a distorted cis-octahedral coordination, formed by two Cl atoms [Ni-Cl 2.4767  (17) and 2.4922  (17)  Å] and four N atoms of two chelate bithiazole ligands [Ni-N 2.069  (5)-2.138  (5)  Å]. The overlapped arrangement and short separation between parallel thiazole rings belonging to neighbouring complexes [3.47  (3)  Å] suggest the existence of - stacking interactions. Short intermolecular SS contacts [3.183  (3)  Å] are also observed. The water molecules are involved in hydrogen bonds with the Cl ligands.
