The electrochemical oxidation of anodic nickel, copper, zinc or cadmium in acetonitrile solutions of Schiff bases (HL) derived from H‐pyrrole‐2‐carbaldehyde and substituted anilines gives compounds of general formula ML 2 . The crystal structure of bis{2‐[(4‐methylphenyl)iminomethyl]pyrrolato}copper(II) has been determined by X‐ray diffraction. The compound crystallizes in the monoclinic space group P2 1 /n with a = 9.356(2), b = 16.697(2), c = 14.145(2) Å and β = 108.47(2)°. The crystal structure consists of monomeric molecules in which the central CuN 4 unit has distorted square‐planar geometry with a dihedral angle of 25.8(3)° between the coordination planes. The IR, 1 H NMR and UV‐visible spectra of the complexes are discussed and related to the structure.
