Benzene-1,3-diammonium bis(pyridine-2,6-dicarboxylato)nickelate(II) pentahydrate

Abstract

In the title compound, (C6H10N2)[Ni(C7H3NO4)2]·5H2O, the NiII ion is six-coordinated by two N and four O atoms from two pyridine-2,6-dicarboxylate ligands in a distorted octahedral fashion. The crystal packing is stabilized by intermolecular O—H...O and N—H...O and weak C—H...O hydrogen bonds and π–π interactions [centroid–centroid distances = 3.4669 (19) and 3.764 (2) Å].
