SPECTROSCOPY OF UNSTABLE COMPLEXES OF ORGANOMETALLIC COMPOUNDS WITH SMALL MOLECULES AT LOW-TEMPERATURES

Using IR spectroscopy, evidence has been obtained that organometallic compounds of transition metals (metallocenes, arenemetaltricarbonyls) and of non-transition elements (alkyl derivatives of II-V group elements) are capable of forming unstable complexes with small molecules (N2, O2, H2, CH4), which can be stabilized at low temperatures. The structure determination of the complexes, using data from the spectra of isotopically substituted compounds, is discussed. © 1990.
