A new double asymmetric μ1,1-azido bridged binuclear copper(II) complex, [Cu2(μ1,1-N3)2(Him2-py)2(N3)2] (Him2-py = 2-(2'-pyridyl)-4,4,5,5-tetramethylimidazoline-1-hydroxy), has been synthesized and characterized structurally and magnetically. The crystal structure shows this complex is binuclear with copper(II) in a distorted square-pyramidal geometry, bridged by double asymmetric end-on azide ligands. The variable temperature magnetic susceptibility analyses reveal weak antiferromagnetic interaction mediated by the bridge. [ABSTRACT FROM AUTHOR]
