Electrical Conduction in Copper(I) Mercaptide Complexes of Aromatic and Heteroaromatic Mercaptans

Electrical conductivities of copper(I) mercaptide complexes of aromatic and heteroaromatic mercaptans have been measured and a conduction mechanism is discussed.The observed conductivities are highly substitution-dependent and vary in the range of 1E-4 to 1E-10 ohm-1 cm-1 at 25 deg C.The solid state absorption spectra and the pressure-induced colour change of the complexes indicate creation of mixed-valence Cu(I)-Cu(II) species which appear to be responsible for their relatively high conductivities.A model which assumes electron hopping assisted by Cu-S stretching frequency along the -Cu-S-Cu-S- conducting spine formed in the S-bridged polymeric structures of these complexes is suggested for the conduction process.
