(Acetato-κO)(2-{[2-(dimethylamino)ethylimino](phenyl)methyl}-5-methoxyphenolato-κ3N,N′,O1)copper(II)

The CuII atom in the title complex, [Cu(C18H21N2O2)(C2H3O2)], is tetracoordinated by two N atoms and two O atoms, of which one O atom is attributed to the acetate group and the other atoms are from the tridentate salicylideneiminate ligand, forming a slight distorted square-planar environment. The other acetate O atom exhibits a very weak intramolecular interaction toward the Cu atom, the Cu—O distance of 2.771 (2) being shorter than the van der Waals radii for Cu and O atoms (2.92 ). Furthermore, there are weak intermolecular interactions, in which the bonding O atom of the acetate group can bridge to the Cu atom of another complex, and the distance of 2.523 (2) is about 0.4 shorter than the van der Waals Cu—O distance in other crystal structures.
