Visible absorption spectra and apparent molar volumes for CoCl2 and Co(ClO4)2 in N,N-diethylacetamide (DEA) as well as the spectra for the Co(ClO4)2 - CoCl2 - DEAand CoCl2- LiCl - DEA systems were studied. The results indicate formation of the electrically neutral CoCl2(DEA)2 complex, being the predominating chloro-complex of cobalt(II) in the solutions of CoCl2 in DEA. The formation constants of the consecutive chloro-complexes of cobalt(II) have been determined: logK1 = 5.28(+-0.10), logK2 =+ - 6.10(_0.08), logK3 = 3.31(+ - 0.05) and logK4 = 0.74(+ - 0.05).
