Abstract

The complex Cu(II)(1R,4S,8R,11S-tmc)2+ comproportionates and isomerizes in the presence of excess of ligand and Cu° in alkaline aqueous solutions to yield Cu(II)(1R,4R,8S,1S-tmc)2+. The visible and EPR spectra of the two complexes as well as their electrochemical properties are reported. The complexes Cu(II)(1R,4R,8S,11S-tmc)(ClO4)2 and [Cu(II)(1R,4S,8R,11S-tmc)]2N3(ClO4) 3 were isolated and crystallographically characterized.
