Structural and mechanistic studies of co-ordination compounds. Part V. The preparation, aquation, and base hydrolysis of octahedral cobalt(III)–amine complexes containing isothiocyanate as an orienting ligand
Abstract
The prepration and characterization of trans-[Co(NH3)4(NCS)Cl]+ cation is described. The kinetics of the aquation and base hydrolysis of this complex cation and those of trans-[Co(cyclam)(NCS)Cl]+ have been studied over a range of temperature. These results are discussed in terms of the influence of nephelaxetic effects of these amine ligands on the central cobalt(III) ion.
