Bismuth phosphide is a proposed inorganic compound with the chemical formula BiP. The structure of this material is unknown.{{cite journal |last1=Carmalt |first1=Claire J. |last2=Cowley |first2=Alan H. |last3=Hector |first3=Andrew L. |last4=Norman |first4=Nicholas C. |last5=Parkin |first5=Ivan P. |title=A synthesis of bismuth(III) phosphide: the first binary phosphide of bismuth |url=https://pubs.rsc.org/en/content/articlelanding/1994/c3/c39940001987 |journal=Journal of the Chemical Society, Chemical Communications |access-date=23 December 2021 |pages=1987–1988 |language=en |doi=10.1039/C39940001987 |date=1 January 1994|issue=17 |url-access=subscription }}
Synthesis
One route entails the reaction of sodium phosphide and bismuth trichloride in toluene (0 °C):{{cite journal |last1=Allen |first1=Geoff C. |last2=Carmalt |first2=Claire J. |last3=Cowley |first3=Alan H. |last4=Hector |first4=Andrew L. |last5=Kamepalli |first5=Smuruthi |last6=Lawson |first6=Yvonne G. |last7=Norman |first7=Nicholas C. |last8=Parkin |first8=Ivan P. |last9=Pickard |first9=Laura K. |title=Preparation and Characterization of a Material of Composition BiP (Bismuth Phosphide) and Other Intergroup 15 Element Phases |url=https://pubs.acs.org/doi/10.1021/cm960606f |journal=Chemistry of Materials |access-date=23 December 2021 |pages=1385–1392 |doi=10.1021/cm960606f |date=1 June 1997|volume=9 |issue=6 |url-access=subscription }}

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.
