Use of [(η-C5R5)M]+ fragments (M = Fe, R = H; M = Ru, R = H, Me) for synthesis of cationic cluster. X-Ray structure of [RuRh3(η-C5Me5)(η-C5H5)3(μ3-CO)3]PF6

Abstract Tetrahedral cationic cluster [MRH3(η-C5R5)(η-C5H5)3(μ3-CO)3]PF6 (M = Fe, R = H; M = Ru, R = H, Me) were synthesized by reaction of [Fe(η-C5H5)(η-Arene)]PF6 or [Ru(η-C5R5)(MeCN)3]PF6 with Rh3(η-C5H5)3(μ-CO)3. Their structure was confirmed by IR and NMR spectroscopy as well as by an X-ray diffraction study of [RuRh3(η-C5Me5)(η-C5H5)3(μ3-CO)3]PF6.

Participation of hydrogen bonds in the protonation of (?5-C5Me5)M(CO)2, M=Ir, Rh

The interaction of Cp*M(CO)2 (M=Ir or Rh) with CF3COOH in low polar media results in partial protonation of these compounds giving molecular (M...HO) and ionic (MH+...O−) hydrogen-bonded complexes. According to IR spectral data, a decrease in temperature results in a shift of the equilibrium toward the ionic forms. These compounds react with phenol to give molecular complexes only.

Synthesis of dicationic triple-decker complexes with a central B-cyclohexyl-substituted borole ligand

Stacking reactions of the dicationic fragments [LM]2+ (LM = (η-C6H6)Ru, (η-C6H3Me3)Ru, or (η-C5Me5)Rh) with the complex (η-C5H5)Co(η-C4H4BCy) (Cy = cyclo-C6H11) afforded new dicationic 30-electron triple-decker complexes [(η-C5H5)Co(μ-η:η-C4H4BCy)ML](BF4)2 containing a cyclohexyl-substituted borole ligand in the central position.

Synthesis of the first unsymmetrical 34-electron cationic cobalt-nickel triple-decker complex with a central cyclopentadienyl ligand [(η-C6Me6)Co(μ-η:η-C5H5)Ni(η-C5H5)]PF6

The first unsymmetrical 34-electron cationic cobalt-nickel triple-decker complex with a central cyclopentadienyl ligand [(η-C6Me6)Co(μ-η:η-C5H5)Ni(η-C5)PF6 was prepared by the reaction of [(η-C6Me6)2Co]PF6 with nickelocene.

Octahedral rhodium cluster [Rh6Cp6(μ6-C)]2+(PF6 -)2

The 86-electron dicationic octahedral rhodium cluster [Rh6Cp6(μ6-C)]2+(PF6-)2 containing Cp ligands and the interstitial carbon atom was synthesized by the reaction of Rh3Cp3(μ-CO)3 with RhCp(C2H4)2

Hydrogen bonds and protonation of carbonyl-containing polynuclear rhodium complexes

AbstractAccording to IR spectroscopy data, the interaction of bi-, tri-, and tetranuclear cyclopentadienylcarbonyl rhodium complexes with rather weak protic acids (phenols, fluoroalcohols) in low-polarity media results in the formation of hydrogen bonds of the OH...O=C type with bridged carbonyl groups. According to1H NMR data, protonation of these complexes with strong acids (CF3COOH and HBF4) occurs at the the Rh-Rh bond to give the symmetrical
