In the title complex, [Mn(C(22)H(18)N(2)O(4))Cl], the Mn(III) centre is in a distorted square-pyramidal configuration, with the basal plane formed by the N(2)O(2) donors of the tetra-dentate 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 tetra-dentate 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 inter-actions link the mol-ecules into wave-like face-to-face double layers along the c direction. A π-π inter-action involving the two outer phenolate rings is observed, the centroid-centroid distance being 3.743 (11) Å.
