(Carbonyl-1?C)bis-[2,3(?)-cyclo-penta-dien-yl][?(3)-(S-methyl trithio-carbonato)methylidyne-1:2:3?C,S'':C:C](triphenyl-phosphine-1?P)(?(3)-sulfido-1:2:3?S)dicobalt(II)iron(II) trifluoro-methane-sulfonate.

ABSTRACT: 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-H?O and C-H?F hydrogen bonds and weak S?O (3.317?Å) and S?F (3.198?Å) inter-actions. The structure is further stabilized by additional inter-molecular C-H?O, C-H?F and O?O (2.942?Å) contacts, together with an unusual S??(Cp) inter-action (S?centroid distance = 3.385?Å), generating an extended network.
