Abstract
According to IR spectroscopy data, the interaction of bi-, tri-, and t etranuclear cyclopentadienylcarbonyl rhodium complexes with rather wea k 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 to H-1 NMR data, protonation of these compl exes with strong acids (CF3COOH and HBF4) occurs at the the Rh-Rh bond to give the symmetrical [GRAPHICS] bridge.
