Mössbauer spectroscopy investigation of Fe(0) compounds with carbon disulfide

The one pot syntheses of the compounds of general formula [Fe(CO)2(h²-CS2 )(L)2] (L = PPh3, P(OPh)3), were carried out in high yields by using trimethylaminoxide (TMNO) as decarbonilating agent. The compounds were investigated by Mössbauer spectroscopy which afforded indicative data of an octahedral geometry around the iron atom in the species [Fe(CO)2(h²-CS2)(PPh3) 2] e [Fe(CO)2(h²-CS2 ){P(OPh)3}2].
