It is a white solid that is used mainly for electroplating zinc but also has more specialized applications for the synthesis of organic compounds. Buy Zinc Cyanide CAS-557-21-1
Structure of Zinc Cyanide CAS-557-21-1
In Zn(CN)2, zinc adopts the tetrahedral coordination environment, all linked by bridging cyanide ligands. The structure consists of two “interpenetrating” structures (blue and red in the picture above). Such motifs are sometimes called “expanded diamondoid” structures. Some forms of SiO2 adopt a similar structure, wherein the tetrahedral Si centres are linked by oxides. The cyanide group shows head to tail disorder with any zinc atom having between one and four carbon neighbours, and the remaining being nitrogen atoms. It shows one of the largest negative coefficients of thermal expansion (exceeding the previous record holder, zirconium tungstate).
Chemical properties of Zinc Cyanide CAS-557-21-1
Typical for an inorganic polymer, Zn(CN)2 is insoluble in most solvents. The solid dissolves in, or more precisely, is degraded by, aqueous solutions of basic ligands such as hydroxide, ammonia, and additional cyanide to give anionic complexes.
Synthesis of Zinc Cyanide CAS-557-21-1
Zn(CN)2 is easy to make by combining aqueous solutions of cyanide and zinc ions, for example via the double replacement reaction between KCN and ZnSO4
