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.
