Abstract
Reactions of [Cu(PPh3)3)X] with the title ligands yield [Cu(PPh3)3(LH)X]. These complexes have been characterised on the basis of analyses, IR, electronic, 1H NMR, conductivity and magnetic measurments. In all cases there is adistorted tetrahedral environment around Cu(I) and the ligands (LH) bind through the thione S-atom to copper(I).
