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-H...O and C-H...F hydrogen bonds and weak S...O (3.317 Å) and S...F (3.198 Å) interactions. The structure is further stabilized by additional intermolecular C-H...O, C-H...F and O...O (2.942 Å) contacts, together with an unusual S...π(Cp) interaction (S...centroid distance = 3.385 Å), generating an extended network.
