Apparent molar volumes of divalent transition metal bromides in dimethyl sulfoxide solutions

Densities and apparent molar volumes for dimethyl sulfoxide solutions of manganese(II), cobalt(II), nickel(II), copper(II) and zinc(II) bromides are reported. The differences in the apparent molar volumes of the salts are discussed and interpreted in terms of bromo-complex formation. An influence of the nature and structure of the metal ion on the coordination state of the salt in solution is discussed.
