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

Abstract

The title complex, [Cu(μ-I)(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 iodo substituents. The nca₂dab acts as a bidentate ligand, coordinating via two N atoms to the copper. The coordination geometry around the Cu atom is a distorted tetrahedron formed by two N atoms from a bidentate diimine ligand and two iodio substituents. The distance between the two Cu atoms is 2.6971(7)Å. The ligand adopts a Z,Z configuration.
