K. Lee, A. J. Lough and I. Manners

Abstract: In the title compound, [Fe(C₅H₅)(C₆H₁₆P₂)(CO)](C₁₂H₁₃BOP), the Fe^II ion adopts a three-legged piano-stool geometry, with FeCg = 1.721 (5)Å (Cg = the centroid defined by the C atoms of the cyclopentadienyl ring). The 1,2-bis(dimethylphosphino)ethane (dmpe) ligand chelates to form a five-membered C₂P₂Fe ring which is in a pseudo-half-chair conformation. In the crystal structure, associations of one cation and two anions are formed via weak intermolecular C-HO hydrogen bonds, giving rise to R₄²(9) rings.
