Abstract: In the title compound, [Cu(C₈H₈NO₃)₂], the nearly planar molecule (r.m.s. deviation = 0.037 Å) is centrosymmetric with the Cu^II atom lying on an inversion center. The Cu^II atom is tetracoordinated, displaying a slightly distorted square-planar geometry. The main deviation from the ideal geometry is seen in the differences in the Cu-O [1.8833 (10) Å] and Cu-N [1.9405 (13) Å] bond lengths, while angular deviations are less than 3°. Intramolecular O-HO and intermolecular Csp²-HO hydrogen bonds form S(5) and R₂²(8) ring motifs, respectively. The latter interaction results in chains of molecules along [100].
