Bis(2-hy-droxy-imino-methyl-6-meth-oxy-phenolato-κ(2)N,O(1))copper(II).

In the title compound, [Cu(C(8)H(8)NO(3))(2)], the nearly planar mol-ecule (r.m.s. deviation = 0.037 Å) is centrosymmetric with the Cu(II) atom lying on an inversion center. The Cu(II) atom is tetra-coordinated, 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°. Intra-molecular O-H⋯O and inter-molecular Csp(2)-H⋯O hydrogen bonds form S(5) and R(2) (2)(8) ring motifs, respectively. The latter inter-action results in chains of mol-ecules along [100].
