Abstract
The structure of (OC)4Fe(PMe2)2Fe(CO)4 has been determined by X-ray diffraction. The molecule has a catenary form and is similar to (OC)3Ni(PPh2)2Ni(CO)3 in that it is centrosymmetric and has a ‘staggered’ conformation of substituents about the M–P and P–P bonds, but differs from this compound in that the P–P bond has a normal length, and is less readily dissociated. The co-ordination round the iron atoms is trigonal bipyramidal, with the axial Fe–C bond lengths significantly shorter than the equatorial; possible reasons for this are discussed.Keywords
