The electronic spectrum of BiCl3 in benzene shows a long-wavelength absorption at lambda(max) = 291 nm which is assigned to a metal-localized sp transition. The excited state is emissive (lambda(max) = 440 nm), bur only at low temperatures (in toluene glasses at 77 K). At room temperature the irradiation of BiCl3 in benzene leads to a redox reaction, which yields elemental bismuth, HCl, biphenyl and chlorobenzene as final photoproducts. It is suggested that the photolysis is induced by a ligand-to-metal charge transfer (LMCT) excited state, which involves the promotion of an electron from weakly coordinated benzene to bismuth(III). This reactive LMCT state is populated from the initially excited sp state by radiationless deactivation.
