Abstract

Thiophene-2-thiocarboxylate complexes of Cu(I), [(Ph3P)2Cu(SCOth)] (1) and H[(Ph3P)2Cu(SCOth)2] (2) (where th = thiophene) were synthesized and characterized structurally by X-ray crystallography. Electronic absorption and emission spectral properties of the two compounds have been studied. Cu(II) complexes, [(TMEDA)Cu(SCOth)2] (3b) and [(Phen)Cu(SCOth)2] (4a) (where TMEDA = tetramethylethylenediamine; Phen = 1,10-phenanthroline) were prepared and characterized by spectroscopic measurements. 3b and 4a underwent desulfurization under ambient conditions readily yielding the corresponding carboxylate complexes [(TMEDA)Cu(O2Cth)2] (3a) and [(Phen)Cu(O2Cth)2·H2O] (4b). 3a and 4b have been characterized crystallographically.
