Abstract

In the title compound, (C3H12N2)[Cu(C7H3NO4)2]·4H2O, the CuII atom is six-coordinated in a distorted octa­hedral geometry by two tridentate pyridine-2,6-dicarboxyl­ate (pydc) ligands. In the crystal, inter­molecular O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds, as well as π–π stacking inter­actions between the pyridine rings of the pydc ligands [centroid–centroid distance = 3.4714 (14) Å] are present. C=O⋯π inter­actions between the carbonyl groups and pyridine rings [O⋯centroid distances = 3.150 (2) and 3.2233 (19) Å] are also observed.
