Gallium(III) cyanide explained

Gallium(III) cyanide is a chemical compound of gallium with the formula Ga(CN)3. It is an air-sensitive white solid that decomposes at 450 °C.

Production and reactions

Gallium(III) cyanide is produced by the reaction of gallium(III) chloride and trimethylsilyl cyanide at 75 °C:

3 Me3SiCN + GaCl3 → 3 Me3SiCl + Ga(CN)3The tetracyanogallate(III) ion can be produced by the reaction of Ga(CN)3 and LiCN or CuCN. It also forms adducts with pyridine to produce Ga(CN)3(NC5H5)2.[1]
