Spectroscopic studies of metal carbonyl complexes. Part II. Dicobalt octacarbonyl

Abstract

Dicobalt octacarbonyl has been studied by i.r. spectroscopy is solution at various temperatures and CO pressures. The nature of the species occurring in solution at temperatures greater than 150 °C and at CO pressures greater than 150 atm is discussed, and a CO-bridged [Co₂(CO)₉] complex, previously suggested, is considered unlikely. The force field for the non-bridged isomer of [Co₂(CO)₈] has been calculated from solution Raman data.
