An interaction of Pd3(NO)2(μ-CF3CO2)4(η2-C6H5Me)2 (I) with alkenes has been studied. A replacement of η2-coordinated arene by various olefins has been found to result in complexes of different nuclearity, Pd3(NO)2(μ-CF3CO2)4(η2-L)2 (L = Me3CCHCH2 (III), CH2CHPh (IV)), Pd4(μ-NO)2(μ-CF3CO2)4(η2-CH2CHPh)4 (V). Complexes IV and V have been characterized by an X-ray diffraction analysis. Molecule IV is constituted of a linear trinuclear metal core bearing η2-coordinated molecules of styrene, terminal nitrosyl and bridging carboxylate groups, whereas, complex V has a tetrahedral core, with η2-coordinated styrene molecules and half-bridging nitrosyl and carboxylate groups. Complex V represents a new type of nitrosyl carboxylate tetrahedral palladium cluster.
The substitution of arene molecules by alkenes in trinuclear Pd3(NO)2(μ-CF3CO2)4(η2-C6H5Me)2 was investigated. The process results in a formation of linear complexes Pd3(NO)2(μ-CF3CO2)4(η2-L)2 (L = trans-stylbene, neohexene, styrene) and tetrahedral clusters Pd4(μ-NO)2(μ-CF3CO2)4(η2-L)4 (L = styrene). The latter is a first example of nitrosyl carboxylate complex with tetrahedral metal core.Figure optionsDownload as PowerPoint slide
