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.^[1]

Production and reactions

Gallium(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]
