In the complex anion of the title compound, (C2H6N5)[Cu(C7H4NO4)(C7H3NO4)]·3H2O, the CuII atom is coordinated by tridentate 6-carb­oxy­pyridine-2-carboxyl­ate and pyridine-2,6-dicarboxyl­ate ligands and is surrounded by four O atoms in the equatorial plane and two N atoms in axial positions in a distorted octa­hedral geometry. In the crystal, the components are linked into a three dimensional network by O—H⋯O, N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonds and a π–π inter­action with a centroid–centroid distance of 3.6080 (8) Å
