Abstract

All three possible diastereoisomers of the title complex have been isolated although one of these apparently occurs only in a folded form with a fifth ligand occupying the basal position of the square pyramid; conversion between diastereoisomers requires additional ligands with the relative stabilities of the diastereoisomers depending upon the donor strength of the medium and, in water, upon the concentration of NaClO4.
