When yellow N4S4 is sublimed in a vacuum over Ag gauze heated to 100°, there is deposited, in that portion of the tube beyond the Ag, which is at about room temp., a very small quant. of a blue subs. which, unlike the yellow sulfide, is insol. in ether, CHCl3, C6H6, or CS2. In H2O it slowly decomps., with KOH it yields NH3, while with Br it gives H2SO4. It decomps. without melting when heated in air and near 188°, the m. p. of the yellow sulfide, turns yellow. Over quartz wool, in a vacuum tube at 300°, there were obtained large bronze crystals with properties like those of the blue product...
