Abstract

The infrared spectra of the copper(I) compounds (C₅H₅)CuPR₃, R = C₂H₅, C₄H₉, and the mercury compounds (C₅H₅)₂Hg and C₅H₅HgCl have been reinvestigated. Comparisons are made with the spectra of compounds which serve as models for pentahapto- and monohaptocyclopentadienylmetal systems. The following conclusions emerge unequivocally: (1) contrary to the belief which has prevailed since 1956, the copper compounds contain pentahapto (i.e., “sandwich-bonded”) rings, and (2) the mercury compounds contain monohapto (i.e., σ-bonded) rings. The significance of these results is discussed in relation to the physical, chemical, and dynamical properties of the molecules.
