OPTICAL LIGAND-TO-LIGAND CHARGE-TRANSFER OF (1,2-DIIMINE)PT(II)(MU-S2MS2) WITH M = MO(VI) AND W(VI)

The binuclear complexes Pt-II(1,2-diimine)(mu-(S2MS2)-S-VI) With 1,2-d iimine = 2,2'-bipyridyl and biacetyl bis(anil) and M = Mo and W show l ong-wavelength absorption bands above 550 nm which are assigned to lig and-to-ligand charge transfer transitions from the bridging sulfide to the diimine ligands.
