Calcium cyanide

Calcium cyanide also known as black cyanide, is the calcium salt of hydrocyanic acid, an inorganic compound with the formula Ca(CN)2. The pure form is a white solid, although rarely observed; commercial samples can be black-gray. It hydrolyses readily (even in moist air) to release hydrogen cyanide. Like other similar cyanides it is very toxic.
