trans-af,bcd,e -ClCl 2 (dien)(A) + . The chloropentaaminecobalt(III) complexes were isolated as ZnCl 2− 4 salts and the green trans -dichloro complexes as the perchlorates. The isomeric purity and composition was established on the basis of C-13 NMR and i.r. spectra and the unsym-fac-cis - geometry was confirmed by the resolution of the complexes with A = n-pentylamine and pyridine.
