Tetra-μ-acetato-κO:O'-bis-{[2-(m-tolyl-amino)pyridine-κN]copper(II)}.

In the crystal structure of the title compound, [Cu(2)(C(2)H(3)O(2))(4)(C(12)H(12)N(2))(2)], the binuclear mol-ecule lies about a center of inversion; the four acetate groups each bridge a pair of Cu(II) atoms. The coordination of the metal atom 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. The pyridine ring is twisted with respect to the benzene ring at a dihedral angle of 45.68 (16)°. Intra-molecular N-H⋯O hydrogen bonding is present between the imino and carb-oxy groups.
