Chemical compound
Bismuth phosphide is a proposed
inorganic compound with the chemical formula BiP. The structure of this material is unknown.
[1]
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.
