ResumoTetrachlorozincate(II) salts of the four (ω, χ, π and ε) possible geometric isomers of the Co(en)(dien)Cl2+ have been synthesised. The π and ε forms contain the dien ligand facial (cis) configuration with the cloro ligand trans to the NH2 and NH groups of the dien respectively. The ω and χ forms contain the dien ligand in the peripherial (trans) configuration with the NH hydrogen of the dien ligand adjacent to and remote from the chloro ligand, respectively. Chemical interconversions of the isomers and their infrared and visible absorption spectra are described.
