Abstract

In the title compound, (C6H10N2)[Co(C7H3NO4)2]·5H2O, the CoII ion is six-coordinated in an N2O4 environment by two pyridine-2,6-dicarboxyl­ate (pydc) ligands, having a distorted octa­hedral geometry. The crystal packing is stabilized by inter­molecular N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds. There are also π–π inter­actions between the pyridine rings of the pydc ligands and between the pydc ligands and the benzene-1,3-diammonium cations, with centroid–centroid distances of 3.4575 (15) and 3.7521 (15) Å.

Highlights
