Iron-rhodium complexes with a single bridging diphosphine ligand: the crystal structure of [CpFe(μ-CO)2(μ-dppm)RhI2]
摘要:
The mononuclear complexes [FeCpI(CO)(2)] 1, [FeCp(CO)(2)(eta(1)-dppm)]I 2, [FeCp(CO)(eta(2)-dppm)]I 3, [FeCp(CO)(2)(eta(1)-dppen)]I 5 and [FeCp(CO)(eta(2)-dppen)]I 6 [dppen = Ph(2)PC(=CH2)PPh(2)] have been synthesised and reacted with [Rh2Cl2(CO)(4)] to produce heterobimetallic complexes of the type [CpFe(mu-CO)(2)(mu-PP)RhX(2)](X = Cl or I). The structure of [CpFe(mu-CO)(2){mu-Ph(2)PCH(2)PPh(2)}RhI2] 4 has been determined by X-ray crystallography.
