Caesium cadmium chloride (CsCdCl3) is a synthetic crystalline material. It belongs to the AMX3 group (where A=alkali metal, M=bivalent metal, X=halogen ions). It crystallizes in a hexagonal space group P63/mmc with unit cell lengths a = 7.403 Å and c = 18.406 Å, with one cadmium ion having D3d symmetry and the other having C3v symmetry.[1]

It is formed when an aqueous solution of hydrochloric acid containing an equimolar solution of caesium chloride and cadmium chloride.[2]
