Abstract :
In the title complex, [Ni(C7H3NO4)(C2H6OS)2(H2O)], the NiII cation is situated on a twofold rotation axis and exhibits a distorted octahedral NO5 coordination environment defined by a tridentate pyridine-2,6-dicarboxylic acid dianion (dpa2−), two dimethyl sulfoxide (DMSO) molecules, and a water molecule. In the crystal, the complex molecules are linked by O—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional network whereby DMSO molecules from neighboring complexes overlap to form layers parallel to (001), alternating with layers of NiII–dpa2− moieties. The title complex is isotypic with its cobalt(II) analogue.
