Alternative Names: Nitrogen sulfide ; 1|E4,3,5|E4,7,2,4,6,8-Tetrathiatetrazocine; 1,3,5,7-tetrathia-2,4,6,8-tetraazacyclooctan-2,4,6,8-tetrayl;

Preparation of tetrasulfur tetranitride

Preparation of tetrasulfur tetranitride

Tetrasulfur tetranitride is prepared by dissolving 1 volume of sulfur dichloride in 8 or 10 volumes of carbon disulfide, cooling, and passing in dry ammonia gas until the dark brown powdery pre­cipitate which forms at first has dissolved and an orange-yellow solution results which contains light-colored flocks of ammonium chloride. These are filtered off and rinsed with carbon disulfide, the solution is evaporated to dryness, and the residue is extracted with boiling carbon disulfide for the removal of sulfur. The un­dissolved material is crude nitrogen sulfide. The hot extract on cooling deposits a further quantity in the form of minute golden-yellow crystals. The combined crude product is recrystallized from carbon disulfide. Tetrasulfur tetranitride could be obtained by the action of ammonia on sulfur monochloride in carbon disulfide, benzene, or ether solution.

Preparation of tetrasulfur tetranitride from sulfur monochloride

Tetrasulfur tetranitride is insoluble in water, slightly soluble in alcohol and ether, somewhat more soluble in carbon disulfide and benzene. It reacts slowly with water at ordinary temperature with the formation of pentathionic acid, sulfur dioxide, free sulfur, and ammonia. Tetrasulfur tetranitride melts with sublimation at 178° C, and explodes at a higher temperature.
