The title complex, [CuCl(C20H18N4O4)(C18H15P)], has two mol-ecules in the asymmetric unit. The Cu atom is four-coordinate in a distorted tetra-hedral geometry, bonded to two imine N atoms of the Schiff base, Cl and PPh3; the main distortion is the small bite angle of the chelating Schiff base ligand. One triphenyl-phospine ligand adopts an approximate propeller conformation, with dihedral angles of 69.36 (14), 77.02 (12) and 82.44 (15)° for pairs of benzene rings, the normals of which make angles of 37.8, 65.4 and 72.6° with the P - Cu bond; the arrangement in the other triphenyl-phosphine ligand is rather less symmetrical, with dihedral angles of 63.41 (15), 70.67 (12) and 78.11 (12)° and angles of 20.3, 78.6 and 83.2° between the ring plane normals and the P - Cu bond. There are inter-molecular C - H⋯Cl and C - H⋯O inter-actions. The crystal was a non-merohedral twin, with approximately equal contributions of the two domains. © International Union of Crystallography 2007.
