text: # Gallium(III) cyanide
  
  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 $Me_3SiCN$ + $GaCl_3$ → 3 $Me_3SiCl$ + $Ga(CN)_3$
  
  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 $Ga(CN)_3(NC_5H_5)_2.$
