Di­aqua­bis­(2-ethyl-5-methyl­imidazole-4-sulfonato-[kappa]2N3,O)nickel(II) dihydrate

A. P. Purdy and R. J. Butcher

Abstract: In the title complex, [Ni(C6H9N2O3S)2(H2O)2]·2H2O, the NiII atom lies on an inversion center and is chelated by N and O atoms of two symmetry-equivalent imidazole­sulfonate ligands in the basal plane, and two water O atoms in axial positions in an overall octa­hedral configuration. The crystal structure displays O-H...O and N-H...O hydrogen bonds, which connect the components into an extended three-dimensional network.
