Crystal structure of the ω-lsomer of chloro(diethylenetriamine)(ethylenediamine)cobalt(III) dichloride hemihydrate

Abstract

Crystals of title compound [isomer (IV)] are monoclinic. space group C2, with Z= 4, in a unit cell of dimensions a= 14.323(1), b= 7.720(1), c= 12.229(1)Å, β= 99.92(1)°. The structure was solved from diffractometer data by Patterson and Fourier methods, and refined by full-matrix least-squares methods to R 0.045 for 2 416 reflections. The cobalt(III) ion is in octahedral co-ordination with the diethylenetriamine ligand adopting a facial (cis) configuration. The co-ordinated chloride ligand is transto the NH group, and the ethylenediamine ligand occupies the remaining two co-ordination sites.
