Mononuclear and tetranuclear zinc benzenethiolate complexes are studied by both Spectroscopic and electrochemical methods. Zn(SPh)42- and Zn4(SPh)102- represent tetrahedral fragments of the cubic zinc sulfide lattice. The structured absorption spectra of the zinc benzenethiolate complexes are ascribed to intraligand transitions for the mononuclear complex and to a composite of both intraligand and ligand-to-metal charge-transfer (LMCT) transitions for the tetranuclear species. The mononuclear complex does not emit, while the tetranuclear compound displays a short-lived metal-to-ligand charge-transfer (MLCT) emission. Photodegradation of both zinc complexes yields thianthrene, dibenzothiophene, and benzenethiol. Zn4(SPh)102- forms a ground-state charge-transfer complex with the dicationic electron acceptor methyl viologen in CH3CN. Excitation of the charge-transfer absorption band with a 30-ps laser pulse leads to the formation of the methyl viologen radical cation showing a lifetime of 2 +/- 0.4 ns.
