Phosphorus tricyanide is an inorganic compound with the chemical formula P(CN)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

Its thermal decomposition can produce graphite phase C3N3P.[3]

Phosphorus tricyanide reacts with [Re(CO)5]+[BF4]− to form {P[CN-Re(CO)5]3}[BF4]3.[4]
