Chlorido{5,5'-dimethyl-2,2'-[1,2-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato-κO,N,N',O'}manganese(III)

Abstract

In the title complex, [Mn(C(22)H(18)N(2)O(2))Cl], the Mn(III) center is in a distorted square-pyramidal configuration; the basal plane is formed by the N(2)O(2) donors of the tetra-dentate Schiff base dianion, with the two phenol O atoms and two imine N atoms each mutually cis. The chloride ion occupies the apical coordination site. The dihedral angle between the two outer phenolate rings of the tetra-dentate ligand is 18.24 (9)°. The central benzene ring makes dihedral angles of 13.71 (8) and 30.50 (8)° with the two outer phenolate rings. In the crystal structure, weak C-H⋯Cl inter-actions link the mol-ecules into screw helices along the b direction. These helices are further connected by weak C-H⋯O inter-actions into a three-dimensional network. The crystal structure is further stabilized by C-H⋯π inter-actions involving the central benzene ring.
