Dimethyl­ammonium diaqua­(pyridine-2,4-dicarboxyl­ato-κ(2) N,O (2))cuprate(II)

The asymmetric unit of the title compound, (C(2)H(8)N)(2)[Cu(C(7)H(3)NO(4))(2)(H(2)O)(2)], contains one-half of a mononuclear [Cu(C(7)H(3)NO(4))(2)(H(2)O)(2)](2−) anion, one dimethyl­ammonium cation and one aqua ligand. The Cu(II) atom, lying on an inversion center, is coordinated by two symmetry-related N atoms and two O atoms from one pyridine-2,4-dicarboxyl­ate ligand and two symmetry-related aqua ligands and exhibits a distorted octa­hedral trans-[CuN(2)O(4)] coordination geometry. Multiple crystallographically independent O—H⋯O and N—H⋯O hydrogen bonds form a three-dimensional network in the crystal structure.
