Reaction of matrix-isolated iron atoms with carbon disulfide
This study was undertaken to determine the type of bonding, as well as the extent of reactivity between CS/sub 2/ and iron atoms. The results of several matrix isolation experiments in which either pure CS/sub 2/ or SC/sub 2//Ar and CS/sub 2//Kr mixtures were condensed with iron atoms and studied by infrared and Moessbauer spectroscopy are presented. All the spectra indicate the presence of only one product of the reaction between Fe and CS/sub 2/ no matter what the composition of the matrix. Conditions were also such that only monomeric Fe complexes were expected; therefore, it is concluded that the complex formed in these matrices has a composition of Fe(CS/sub 2/). Results of annealing experiments carried out to determine the stability of the complex were interpreted to mean that the Fe(CS/sub 2/) formed in a 100% CS/sub 2/ matrix is stable to at least 60 K, begins to decompose between 60 and 80 K to form a new iron-containing species, and forms a very stable, nonvolatile residue at room temperature. 22 references, 1 figure.
