Silver cyanate is a chemical compound; it is the cyanate salt of silver.

It can be prepared by the reaction of potassium cyanate or urea with silver nitrate.[1]

${\displaystyle \mathrm {AgNO_{3}+KOCN\longrightarrow AgOCN\downarrow +\ KNO_{3}} }$
${\displaystyle \mathrm {AgNO_{3}+H_{2}N{\text{-}}C(O){\text{-}}NH_{2}\longrightarrow } }$ ${\displaystyle \mathrm {AgOCN\downarrow +\ NH_{4}NO_{3}} }$

Silver cyanate is a beige to gray powder. It crystallises in the monoclinic crystal system in space group P21/m with parameters a = 547.3 pm, b = 637.2 pm, c = 341.6 pm, and β = 91°.[2]

With nitric acid, silver cyanate reacts to form carbon dioxide and ammonium nitrate.[3]

${\displaystyle \mathrm {AgOCN+2HNO_{3}+H_{2}O\longrightarrow } }$
${\displaystyle \mathrm {AgNO_{3}+CO_{2}\uparrow +\ NH_{4}NO_{3}} }$
