Abstract: The asymmetric unit of the title compound, [FeCo2(C5H5)2(C3H3S3)S(C18H15P)(CO)]CF3SO3, consists of a triangular irondicobalt cluster cation and a trifluoromethanesulfonate anion. In the cation, the FeCo2 triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithiocarbonate residue that bridges the Fe-C bond. Each Co atom carries a cyclopentadienyl ligand while the Fe atom coordinates to one carbonyl and one triphenylphosphine ligand. In the crystal structure, the cation is linked to the anion by a number of weak non-classical C-HO and C-HF hydrogen bonds and weak SO (3.317 Å) and SF (3.198 Å) interactions. The structure is further stabilized by additional intermolecular C-HO, C-HF and OO (2.942 Å) contacts, together with an unusual S(Cp) interaction (Scentroid distance = 3.385 Å), generating an extended network.
