Phosphorus tricyanide is an inorganic compound with the chemical formula P(C N)₃. It can be produced by the reaction of phosphorus trichloride and trimethyl(iso)cyanosilane.^[2]^{[clarification needed]} The reaction of phosphorus tribromide and silver cyanide in diethyl ether produce phosphorus tricyanide too.^[1]

PBr₃ + 3 AgCN → P(CN)₃ + 3 AgBr
