Abstract: The title complex, [CuCl(C₂₀H₁₈N₄O₄)(C₁₈H₁₅P)], has two molecules in the asymmetric unit. The Cu atom is four-coordinate in a distorted tetrahedral 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 triphenylphospine 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 triphenylphosphine 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 intermolecular C-HCl and C-HO interactions. The crystal was a non-merohedral twin, with approximately equal contributions of the two domains.
