Résumé

A spectrophotometric investigation of cobalt(II) chloro complexes was carried out in ethanol and propan-2-ol at 25 °C and at constant ionic strength of 1 mol l−1. Three mononuclear complexes are identified in both the solvents: CoCl+, CoCl2 and COCl3− and the respective apparent overall stability constants are calculated. The calculated values in ethanol are: log β1=1.3, log β2=2.8, log β3=4.1; in propan-2-ol: log β1=1.7, log β2=3.3, log β3=4.7. Stability is higher in the higher alcohol. Individual electronic spectra of all species in both the solvents are calculated and reported here for the first time.
