Dicarbonyl-dichloridobis(trimethyl-phosphane)iron(II)-carbonyl-dichlorido-tris(trimethyl-phosphane)iron(II)-tetra-hydro-furan (1/1/2).

The asymmetric unit of the title crystal, [FeCl(2)(C(3)H(9)P)(3)(CO)]·[FeCl(2)(C(3)H(9)P)(2)(CO)(2)]·2C(4)H(8)O, contains half mol-ecules of the two closely related Fe(II) complexes lying on mirror planes and a tetra-hydro-furan solvent mol-ecule, one C atom of which is disordered over two sets of sites with site occupancy factors 0.633 (9) and 0.367 (9). In both Fe(II) complex mol-ecules, a distorted octa-hedral coordination geometry has been observed around the Fe atoms. Weak intermolecular C-H⋯O inter-actions are observed in the crystal structure.
