Abstract: In the title complex, [NaCu(C₂₂H₁₈N₂O₄)Cl(CH₃OH)], the Cu atom lies nearly in the plane defined by the N₂O₂ 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 intermolecular C-HCl and O-HCl hydrogen bonds, which link the molecules into dimers. The crystal packing is further stabilized by weak - stacking interactions [centroid-centroid distances of 3.442 (4), 3.482 (3), 3.350 (2), 3.531 (4) 3.575 (2) and 3.604 (2) Å].
