Cadmium cyanide is an inorganic compound with the formula Cd(CN)2.

Cyanide ligands interconnect pairs of metal centers.

This structural similarity of cadmium dicyanide and cristobalite was foundational in the development of mineralomimetic chemistry: "the build-up of mineral-like structures using materials that never give stable minerals.

With acids, its solutions evolve hydrogen cyanide.

When it is crystallizes in the presence of certain small molecules, it forms clathrates.
