Di-μ-iodo-bis{[bis(trans-cinnam­aldehyde)­ethyl­enedi­imine-κ²N,N′]copper(I)}

The title complex, [Cu(μ-I)(ca₂en)]₂ [ca₂en is N,N′-bis(trans-cinnam­aldehyde)­ethyl­enedi­imine, C₂₀H₂₀N₂], has a dimeric structure where two copper(I) ions are doubly bridged by iodine substituents. The inversion center is located midway between the two Cu atoms. The ca₂en 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 iodine substituents. The distance between the two Cu atoms is 2.635 (2) Å. The ca₂en ligand adopts a Z,Z configuration.
