摘要：

Densities and apparent molar volumes for DMSO solutions of manganese(II), cobalt(II), nickel(II), copper(II), zinc(II) perchlorates and chlorides are reported. The limiting partial molar volumes of the hexakis-(DMSO) cations are derived and discussed in terms of the ligand field effects. The differences between volumetric properties of DMSO solutions of perchlorates and chlorides are interpreted in terms of formation of the respective chloride-complexes of the divalent transition metal cations.
