[1] It is a white solid that undergoes hydrolysis to produce aluminium hydroxide and hydrogen cyanide.

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

[1] The compound was produced in 2001 by the reaction of lithium tetrachloroaluminate and trimethylsilyl cyanide in diethyl ether.

Its atoms form a lattice, and X-ray crystallography shows that its crystals form an octahedral Prussian-blue-like structure.
