Conclusions

The crystal structure of Pt4(CO)5(PEt3)4 was determined and the IR spectra of this compound in the VCO region characteristic for such clusters were studied. Four models for the interaction of CO with metals upon adsorption were proposed on the basis of the geometrical parameters obtained for the coordination of CO in this and other clusters. Calculation of the frequencies and shape of the vibrations of all four models showed that we must independently evaluate the force constants of the interaction of the CO groups with the remaining part of the complex in order to develop reliable spectral indicators for the specific type of CO coordination.
