Silver cyanate

Silver cyanate can be made by the reaction of potassium cyanate with silver nitrate in aqueous solution.

${\displaystyle {\ce {{AgNO3}+{KNCO}\rightarrow {Ag(NCO)}+{K+}+{NO3^{-}}}}}$

Alternatively, the reaction

${\displaystyle {\ce {{AgNO3}+{H2N-C(O)-NH2}\rightarrow {AgNCO}+{NH4NO3}}}}$

analogous to the reaction used for the industrial production of sodium cyanate, may be used.

The crystal structure has been determined.[1] The are chains of silver atoms bridged by the nitrogen atom of cyanate ions.

Silver cyanate reacts With nitric acid to form silver nitrate, carbon dioxide, and ammonium nitrate.[2]

${\displaystyle {\ce {{AgNCO}+{2HNO3}+H2O\rightarrow {AgNO3}+CO2{\uparrow }+NH4NO3}}}$
