Structure, synthesis, reactivity

In terms of its structure, nitrosyl cyanide is planar. It is strongly bent at the internal nitrogen, analogous to the structure of nitrosyl chloride. The C-N-O angle is 113°. The NCN angle is 170°.[1]

The compound can be generated by the reaction of nitrosyl chloride and silver cyanide at low temperatures. It is not typically isolated, but trapped by Diels-Alder reactions, e.g. with butadiene. Cycloadditions occur across the N=O bond. It forms a reversible adduct with 9,10-dimethylantracene.[1]

  • Nitryl cyanide (O2NCN), a colorless gas (b.p. 7 °C).[3]
