Diaqua­bis­(4-hy­droxy-5-nitro­pyridine-2-carboxyl­ato-κ(2) N (1),O (2))copper(II)

In the title compound, [Cu(C(6)H(3)N(2)O(5))(2)(H(2)O)(2)], the Cu(II) ion, lying on an inversion center, is coordinated by two pyridine N atoms and two carboxyl­ate O atoms from symmetry-related two 4-hy­droxy-5-nitro­pyridine-2-carboxyl­ate ligands, and two water mol­ecules, forming a distorted octa­hedral geometry. In the crystal, O—H⋯O hydrogen bonds link the complex mol­ecules. One of the H atoms of the water mol­ecule is disordered over two sites of equal occupancy.
