| Summary: | In the title compound, [Ni(C9H4O6)(C12H12N2)(H2O)2]·7H2O, the NiII atom is six-coordinated by two O atoms from a chelating carboxylate group of a 5-carboxybenzene-1,3-dicarboxylate ligand, two O atoms of two water molecules and two N atoms from a 6,6′-dimethyl-2,2′-bipyridine ligand in a distorted octahedral geometry. The compound exhibits a three-dimensional supramolecular structure composed of the complex molecules and lattice water molecules, which are linked together by intermolecular O—H...O hydrogen bonds and partly overlapping π–π interactions between the pyridine and benzene rings [centroid–centroid distances = 3.922 (2) and 3.921 (2) Å]. One of the lattice water molecules is disordered over two positions in an occupancy ratio of 0.521 (6):0.479 (6). |
