This work describes the one pot syntheses and characterization of two new heterometallic carbonyl compounds of the type [Fe(CO)3(m-CS2)(PPh3 )(CuX)], X = Cl, ClO4. Both compounds were investigated by infrared and 31P{¹H} NMR spectroscopies in order to clarify the coordination mode of the carbonyl groups, as well the bridging disposition of the carbon disulfide between iron (0) and copper (I) atoms.
