High-pressure synthesis of crystalline carbon nitride imide, C 2N2(NH)

(Figure Presented) Extreme chemistry: The carbon nitride imide C 2N2(NH) is synthesized from the single-source precursor 1-cyanoguanidine under high-pressure and high-temperature conditions in a laser-heated diamond-anvil cell. Characterization of single crystals recovered at ambient conditions reveals that the new compound adopts a defect wurtzite structure (see picture).

Nitrosation of Cyanamide: Preparation and Properties of the Elusive E- and Z-N'-Cyanodiazohydroxides

Nitrosation of cyanamide leads to unstable E/Z-cyanodiazohydroxides that easily deprotonate to E/Z-cyanodiazotates. Pursuing observations of E. Drechsel 145 years ago, the structure and reactivity of those products was determined, mainly in aqueous solution. Depending on the pH, three different thermal decomposition pathways give either N2O + HCN or N2 + HNCO. They were evaluated experimentally and by quantum mechanical calculations.
