Preparation, properties, and reactions of some sulphatobis(ethylenediamine)cobalt(III) complexes
Abstract
Previously reported sulphatobis(ethylenediamine)cobalt(III) complexes have been shown to be complex mixtures. A number of pure, nonionic compounds have been isolated from these, either in the solid state or in solution, and have been characterised by visible and i.r. spectroscopy. The kinetics of their solvolytic aquation and base hydrolysis have been investigated, and the labilising influence of the sulphato-ligand is briefly discussed. The behaviour of sulphate as a replaced ligand is compared with that of chloride.
