Chlorido{5,5′-dimethoxy-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenolato-κ4 O,N,N′,O′}manganese(III)

In the title complex, [Mn(C22H18N2O4)Cl], the MnIII centre is in a distorted square-pyramidal configuration, with the basal plane formed by the N2O2 donors of the tetradentate Schiff base dianion; the two phenolate O atoms and the two imine N atoms are each mutually cis. The chloride ion occupies the apical position. The dihedral angle between the two outer phenolate rings of the tetradentate Schiff base ligand is 16.44 (9)°. The central benzene ring makes dihedral angles of 10.64 (9) and 25.17 (10)° with the two outer phenolate rings. In the crystal structure, weak C—H⋯O and C—H⋯Cl interactions link the molecules into wave-like face-to-face double layers along the c direction. A π–π interaction involving the two outer phenolate rings is observed, the centroid–centroid distance being 3.743 (11) Å.
