Crystal structure of Di-μ-bromo-bis{[bis(2-nitrocinnamaldehyde)-2,2′-diiminobiphenyl-N,N′]copper(I)}

Abstract

The title complex, [Cu(μ-Br)(nca2dab)]2 [nca2dab is N,N′-bis(2-nitrocinnamaldehyde)-2,2′-diiminobiphenyl], has a dimeric structure, where two copper(I) ions are doubly bridged by bromo substituents. The coordination geometry around the Cu atom is a distorted tetrahedron formed by two N atoms from a bidentate nca2dab ligand and two bromo substituents. The distance between the two Cu atoms is 2.6650(8)Å. The nca2dab ligand adopts a Z,Z configuration. 2006 © The Japan Society for Analytical Chemistry.
