Tetra-?-acetato-?O:O'-bis-{[4-methyl-2-(m-tolyl-amino)pyridine-?N]copper(II)}.

ABSTRACT: In the crystal structure of the title binuclear complex, [Cu(2)(CH(3)COO)(4)(C(13)H(14)N(2))(2)], the four acetate groups each bridge a pair of Cu(II) atoms. The coordination of the metal atoms is distorted square-pyramidal, with the bonding O atoms comprising a square basal plane and the coordinating N atom of the N-heterocycle occupying the apical position. In the two N-hetercycle ligands, the benzene rings are twisted with respect to the pyridine rings, making dihedral angles of 53.1?(2) and 54.2?(2)°. Intra-molecular N-H?O hydrogen bonding is present between the imino and carb-oxy groups. The crystal studied was a non-merohedral twin with a minor twin component of 21.4%.
