Aluminium cyanide is a metallic cyanide with a chemical formula of Al(CN)3.[1] It is a white solid that undergoes hydrolysis to produce aluminium hydroxide and hydrogen cyanide.[2]

Synthesis and properties[edit]

Aluminium cyanide was first produced in 1924 as its ammoniate, Al(CN)3·5NH3, by reacting aluminium metal and mercury(II) cyanide in liquid ammonia to prevent hydrolysis.[1]

2 Al + 3 Hg(CN)2 → 2 Al(CN)3 + 3 Hg

When the ammoniate contacts water, it produces aluminium hydroxide, ammonia, and ammonium cyanide.[1]

The pure compound was produced in 2001 by the reaction of lithium tetrachloroaluminate and trimethylsilyl cyanideindiethyl ether and its crystals form an octahedral Prussian-blue-like structure.[3]
