摘要
In the title compound, [Ni(C12H6N2O4)(H2O)(2)], the NiII atom (site symmetry 2) displays a distorted cis-NiN2O4 octahedral coordination geometry with two N atoms and two O atoms of the tetradentate 2,2'-bipyridine-6,6'-dicarboxylate ligand in the equatorial plane and two water molecules in axial positions. The complete dianionic ligand is generated by crystallographic twofold symmetry. In the crystal, a two-dimensional supramolecular structure parallel to (001) is formed through O-H...O hydrogen-bond interactions between the coordinated water molecules and the O atoms of nearby carboxylate groups.
