One Dinuclear Copper(II) Complex: Synthesis, Structure, and Properties

Abstract

The reaction of Cu(AC)2·H2O with 4-diethylamino-2-hydrogen-benzaldehyde (Hdahb) in methanol and water under solvothermal conditions leads to the formation of a novel dinuclear complex [Cu2(dahb)4] (1) (C44H56Cu2N4O8, Mr = 896.03, Dcalcd = 1.404 g cm−3). The compound belongs to the monoclinic system space group P21/c, and was characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. It consists of dinuclear unit, which is bridged by μ2-phenolato oxygen. The {Cu2IIO2} core displays dominant antiferromagnetic interactions from the nature of the binding modes through μ2-O.[Supplemental materials are available for this article.
