Abstract
The complex Cu(II)(1R,4S,8R,11S-tmc)(2+) comproportionates and isomerizes i n the presence of excess of ligand and Cu degrees in alkaline aqueous solut ions to yield Cu(II)(1R,4R,8S,1S-tmc)(2+). The visible and EPR spectra of t he 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-tm c)](2)N-3(ClO4)(3) were isolated and crystallographically characterized. (C ) 2001 Elsevier Science B.V.
