RESUMO
The asymmetric unit of the title compound, [FeCo(2)(C(5)H(5))(2)(C(3)H(3)S(3))S(C(18)H(15)P)(CO)]CF(3)SO(3), consists of a triangular irondicobalt cluster cation and a trifluoro-methane-sulfonate anion. In the cation, the FeCo(2) triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithio-carbonate residue that bridges the Fe-C bond. Each Co atom carries a cyclo-penta-dienyl ligand while the Fe atom coordinates to one carbonyl and one triphenyl-phosphine ligand. In the crystal structure, the cation is linked to the anion by a number of weak non-classical C-Hâ¯O and C-Hâ¯F hydrogen bonds and weak Sâ¯O (3.317â Å) and Sâ¯F (3.198â Å) inter-actions. The structure is further stabilized by additional inter-molecular C-Hâ¯O, C-Hâ¯F and Oâ¯O (2.942â Å) contacts, together with an unusual Sâ¯π(Cp) inter-action (Sâ¯centroid distance = 3.385â Å), generating an extended network.
