Tetra-μ-benzoato-bis[(6-methylquinoline)copper(II)]

Abstract

In the title compound, [Cu2(C7H5O2)4(C10H9N)2], the paddle-wheel-type dinuclear complex is constructed by four bridging benzoate groups and two terminal 6-methylquinoline ligands. The asymmetric unit contains one-half of the whole molecule, and there is an inversion center at the mid-point of the Cu...Cu bond. The octahedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by the N atom of the 6-methylquinoline molecule [Cu—N = 2.212 (2) Å] and by another Cu atom [Cu...Cu = 2.6939 (13) Å]. The Cu atom lies 0.234 Å out of the plane of the four O atoms. The molecular packing is stabilized by one intramolecular C—H...O as well as C—H...π and π–π interactions.
