Abstract

Abstract: Three kinds of RCCo₃ (CO)₉ and their radicals have been studied with electrochemistry and ESR spectra. The reduction of RCCo₃ (CO)₉ are related to the nature of R and RCCo₃ (CO)₉^· are stable at room temperature. Based on the symmetry analysis of MO, the ESR spectra of cluster radicals are discussed in detail. The sign of hyperfine coupling constant and the nature of the orbital occupied by unpaired electron are determined. Furthermore, the spin density on 3d orbital and 4s orbital of cobalt are calculated from experimental results.

Key words: Cobalt, Trinuclcar carbonyl cluster, Cyclic voltammetry, ESR
