Abstract
The solubilities of mercuric halides in series of paraffinic and aromatic solvents and in dioxane, as well as in mixtures of these solvents, have been measured. The results are discussed in terms of solvent—solute interactions and their influence on the configuration of the mercuric halides in solution. The solubility trends in pure aromatic solvents show similarities to the behavior of the iodine—aromatic solvent and silver salt—aromatic solvent systems. It is suggested that donor—acceptor complexes are formed between the mercuric halides and some of the solvents examined. The solubilities in mixed solvents indicate a 2:1 solvent:solute ratio which suggests distorted tetrahedral mercuric halide—solvent complexes. In some cases mixed solvates seem to be formed.
