Synthesis
One route entails the reaction of sodium phosphide and bismuth trichloride in toluene (0 °C):[2]
- Na3P + BiCl3 → BiP + 3 NaCl
Another method uses tris(trimethylsilyl)phosphine in place of the sodium phosphide.
Physical properties
When heated in air, bismuth phosphide burns.
When heated in an atmosphere of carbon dioxide, a gradual volatilization of phosphorus is observed.
Chemical properties
This compound is oxidized when boiled in water.
All strong acids dissolve it.
