Tetrasulfur dinitride preparation

Tetrasulfur dinitride can be prepared by (a) treatment of [(Me3Si)2N]2S with equimolar amounts of SC12 and S2C12,48 (b) the reaction of the trisulfane S3[N(SiMe3)2]2 with a mixture of S2C12 and S0C12,49 (c) the decomposition of... 

As with the preparation of tetrasulfur tetranitride, caution must be observed tetrasulfur dinitride decomposes explosively at temperatures of ca. 30°, and on grinding with only slight pressure very violent detonations can occur. It should also be noted that at room temperature the substance undergoes appreciable polymerization in a short time. 

This compound is prepared by the reaction of tetrasulfur tetranitride with sulfur. An autoclave, fitted with a magnetic stirrer and capable of being heated to 100°, is used as the reaction vessel. A mixture of 24 g. of tetrasulfur tetranitride and 50 g. of sulfur is suspended or, respectively, dissolved in 380 ml. of pure carbon disulfide. The mixture is heated in the autoclave for 2 hours at 110° and then cooled rapidly. It is then filtered from the polythiocyanogen which is formed under these conditions, and the residue washed well with carbon disulfide. These washings are added to the original filtrate, and this is then evaporated in vacuum. The red residue after removal of carbon disulfide is distilled in high vacuum with a bath temperature of 60 to 65°, whereupon dark red crystals separate in the receiver (f.p. 23°). It is found that the best yields are obtained when the walls of the autoclave are soiled from a previous preparation, in which case about 4 g. of tetrasulfur dinitride is usual.
