Guanidine Azidodithiocarbonate

Guanidine Azidodithiocarbonate, HNC(NH2)2 HSCSNj, mw 178.25, N 47.15% col prisms, mp 88-90° (dec) readily sol in w or acet, sol in ale and almost insol in eth. It was prepd by interacting aq guanidine carbonate with freshly prepd solid azidodithiocarbonic acid or by reacting aq guanidine azide, HNC(NHa) -HNS, with purified CSa... 

When heated on a Pt foil, guanidine azidodithiocarbonate decomposes rapidly, with evolution of much gas, but without deton... 

Like the inorg compds of the azido acid, and unlike the alkyl and aryl derivs, the guanidine salt is photosensitive. In the dark it may be stored below 10°, in vacuo, for days without appreciable decompn. On long standing at RT, the salt decomps quanty, yielding Na, sulfur and guanidine thiocyanate. In aq soln the azido salt reacts with AgNOs to form the insol Ag azidodithiocarbonate...
