Abstract

In situ infrared spectroelectrochemistry [SNIFTIRS (subtractively normalized interfacial FTIR spectroscopy)] has been used to obtain spectra at a platinum electrode of the reduction products of [Co3(CPh)(CO)9] in absolute methanol, in CO saturated methanol, in the presence of a ligand [P(C6H4SO3-m)3]3– (L) and in dichloromethane. The cluster species 49e [Co3(CPh)(CO)9]˙–, 50e [Co3(CPh)(CO)9]2– and, tentatively, the 47e [Co3(CPh)(CO)8]– and 49e [Co3(CPh)(CO)8L]˙– were identified and their interrelationships elucidated. Adsorption of the cluster at the surface may be responsible for the unexpected formation of CO2 upon decomposition of Co(CO)4–.
