{μ-6,6'-Dimeth-oxy-2,2'-[1,2-phenyl-ene-bis(nitrilo-methyl-idyne)]diphenolato}methano-lcopper(II)sodium(I)

In the title complex, [NaCu(C(22)H(18)N(2)O(4))Cl(CH(3)OH)], the Cu atom lies nearly in the plane defined by the N(2)O(2) core of donor atoms, the out-of-plane distance being 0.001 (2) Å. The anion provides a planar cavity of four O atoms which accommodates a sodium cation. The coordination geometry around sodium is completed by the methanol O atom and a chloride ion. The four O atoms define a coordination plane containing the sodium cation [maximum displacement from the mean plane through the five atoms = 0.152 (3) Å for Na]. The crystal structure is stabilized by inter-molecular C-H⋯Cl and O-H⋯Cl hydrogen bonds, which link the mol-ecules into dimers. The crystal packing is further stabilized by weak π-π stacking inter-actions [centroid-centroid distances of 3.442 (4), 3.482 (3), 3.350 (2), 3.531 (4) 3.575 (2) and 3.604 (2) Å].
