Resumen

The reaction of 2 equiv of [Rh(COD)(acetone)2]+ with the dianionic homoleptic species [Pt(C≡CR)4]2- (R = But (1a), SiMe3 (1b)) in acetone (molar ratio 2:1) gives the expected neutral trinuclear adducts {Pt(μ-C-C≡CR)4[Rh(COD)]2} (R = But (2a), SiMe3 (2b)) in moderately good yield. Further reaction of 2a with the binuclear [Rh(μ-X)(COD)]2 (X = Cl, OH) derivatives (molar ratio 1:1) produces the formation of unusual pentanuclear {Pt(μ-C=CBut)4-[Rh2(μ-X)(COD) 2]2} complexes (X = Cl (3a), OH (4a)), which are formed by a dianionic "Pt-(C≡CBut)4" fragment and two dinuclear cationic "Rh2(COD)2(μ-X)" units connected through bridging alkynyl ligands. The molecular structures of complexes 3a and 4a have been established by X-ray crystallography.
