Reaction of [CpRu(CH3CN)3]PF6 with bidentate ligands: structural characterization of [{CpRu(CH3CN)2}2(μ-η1:1-dppe)](PF6)2 [dppe=1,2-bis(diphenylphosphino)ethane]
摘要:
The reaction of [CpRu(CH3CN)(3)]PF6 with the bidentate ligands L-L = 1,2-bis(diphenylphosphino)ethane, dppe, and (1-diphenylarsino-2-diphenylphosphino)ethane, dpadppe, affords mononuclear or dinuclear complexes of formula [CpRu(eta(2)-L-L)(CH3CN)]PF6, [{CpRu(CH3CN)(2)}(2)(mu-eta(1:1)-L-L)](PF6)(2) and [{CpRu(CH3CN)}(2)(mu-eta(1:1)-L-L)(2)](PF6)(2) (L-L=dppe, dpadppe). All of the compounds are characterized by microarialysis and NMR [H-1 and P-31{H-1}] spectroscopy. The crystal structure of [{CpRu(CH3CN)(2)}(2)(mu-eta(1:1)-dppe)](PF6)(2) has been determined by X-ray diffraction analysis. The complex exhibits a dppe ligand bridging two CpRu(CH3CN)(2) fragments.
