Tetra-μ-acetato-κ⁸O:O′-bis{[4-methyl-N-(4-methylphenyl)pyridin-2-amine-κN¹]copper(II)}

Abstract

The title complex, [Cu2(CH3COO)4(C13H14N2)2], features a binuclear mol­ecule, which lies about a crystallographic centre of inversion; the four acetate ions each bridge a pair of CuII atoms. The coordination of the metal atom is distorted octa­hedral within a donor set defined by four O atoms, the heterocyclic N atom and the second Cu atom. The pyridine ring is twisted with respect to the tolyl ring and forms a dihedral angle of 35.34 (9)°. A bifurcated N—H⋯(O,O) hydrogen bond is present, linking the amine group to two carboxyl­ate O atoms derived from different acetate ions. In the crystal, C—H⋯π inter­actions link mol­ecules into a supra­molecular array in the bc plane.

“…The Cu-N complexes have occupied an important position in catalytic processes. In connection with on-going studies into the structural characterization of tetrakisacetatobis[(substituted 2-aminopyridyl)copper] complexes (Fairuz et al, 2010;Chang et al (2011), the title complex, (I), was investigated. The binuclear copper(II) complex, Fig.…”
