The results of a study of the electronic absorption spectrum of cobalt(II) in Li2SO4–DMSO solution, an equimolar NaHSO4–KHSO4 melt, a eutectic melt of Li2SO4–Na2SO4–K2SO4, single salt melts of Li2SO4 and Na2SO4 and a doped single crystal of K2Zn2(SO4)3 have been combined with previous results in sulfate media; all the results can be explained in terms of a blue dodecahedral [Co(O2SO2)4]6− species, a pink octahedral [Co(OSO3)6]10− species or an equilibrium mixture of the two.
