Caesium cyanide (chemical formula: CsCN) is the caesium salt of hydrogen cyanide. It is a white solid, easily soluble in water, with a smell reminiscent of bitter almonds, and with crystals similar in appearance to sugar. Caesium cyanide has chemical properties similar to potassium cyanide and is very toxic.
Production
[edit]Hydrogen cyanide reacts with caesium hydroxide giving caesium cyanide and water:[2]
- HCN + CsOH → CsCN + H2O
