Abstract The solubilities of heptasulfur imide in eleven organic solvents were measured. The solubility parameter of heptasulfur imide was estimated to be 12.7 at 25 °C from the solubilities and the activity deduded from the enthalpy of the fusion; we assumed the solutions to be regular.
Abstract The solubilities of tetrasulfur tetranitride in thirteen organic solvents were measured. The solubility parameter of tetrasulfur tetranitride was estimated from the solubilities and its deduced activity to be 13·7 at 25 °C; we assumed it to be regular.
