Rubidium cyanide (chemical formula: RbCN) is the rubidium salt of hydrogen cyanide. It is a white solid, easily soluble in water, with a smell reminiscent of bitter almonds, and somewhat similar in appearance to sugar. Rubidium cyanide has chemical properties similar to potassium cyanide, and is similarly very toxic.

Production[edit]

Rubidium cyanide can be synthesized by the reaction of hydrogen cyanide and rubidium hydroxide in alcohol or ether:[2]

HCN + RbOH → RbCN + H2O.
