Silver cyanate can be made by the reaction of potassium cyanate with silver nitrate in aqueous solution, from which it precipitates as a solid.

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

Alternatively, the reaction

{\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 consists of chains of silver atoms bridged by the nitrogen atom of cyanate ions.[1]

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

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