The iron trithiocarbonato complex CpFe(CO)2(κS-SCS2Ph) (1a) and its selenodithiocarbonato analogue CpFe(CO)2(κSe-SeCS2Ph) (1b) were generated by room temperature reactions of (μ-Ex)[CpFe(CO)2]2 (E = S; x = 2, 3. E = Se; x = 1) with PhSC(S)Cl. These compounds can be converted into the complexes CpFe(CO)(κ2S,E-ECS2Ph) [E = S (2a), Se (2b)], in which the trithiocarbonato or the selenodithiocarbonato ligand is bonded to the iron in a chelate form, under photolytic conditions. The composition and structure of all products have been verified by elemental analyses, IR and 1H NMR spectroscopies. The crystal structures for compounds 1a, 1b, and 2b show a three-legged piano-stool configuration at Fe in each complex. The spectroscopic and structural data in this work are commensurate with the electronic factor of the S- and Se-donor ligands.
