Production and reactions
editGallium(III) cyanide is produced by the reaction of gallium(III) chloride and trimethylsilyl cyanide at 75 °C:[1]
- 3 Me3SiCN + GaCl3 → 3 Me3SiCl + Ga(CN)3
The 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][3]
