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, D_calcd = 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 {Cu₂^IIO₂} core displays dominant antiferromagnetic interactions from the nature of the binding modes through μ₂-O.
