(Acetato-κO)(2-{[2-(dimethyl­amino)­ethyl­imino](phen­yl)meth­yl}-5-methoxy­phenolato-κ(3) N,N′,O (1))copper(II)

The Cu(II) atom in the title complex, [Cu(C(18)H(21)N(2)O(2))(C(2)H(3)O(2))], 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) Å being shorter than the van der Waals radii for Cu and O atoms (2.92 Å). 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) Å is about 0.4 Å shorter than the van der Waals Cu—O distance in other crystal structures.
