Description and references

Prepd by the interaction of disulfur dichloride and ammonia: Becke-Goehring, Inorg. Synth. 6, 124 (1960).

Properties

Orange-red, monoclinic needles from benzene, mp 178°. Additional purification by sublimation in high vacuum, (bath temp 100°), mp 180°. bp760 ≈185°. Further heating results in deflagration and explosion. Practically insol in cold water, hydrolyzed by boiling water. Slightly sol in benzene, abs ethanol, carbon disulfide. Handle with caution: May dec explosively on striking or at temps much above 100°.
