General description

Copper(I) cyanide is a copper salt containing cyanide (a potential ligand). It can be prepared by reacting copper vapor with cyanogen (NCCN) in vapor phase. It forms novel diamine complexes by reacting with various diamine ligands via “thiosulfate-assisted” synthesis method. It affords crystalline complexes by reaction with thiourea ligands.

Application

Copper(I) cyanide may be used in the preparation of copper(I) cyanide salt (K3Cu(CN)4).
