Preparation and characterization of a material of composition BiP (Bismuth Phosphide) and other intergroup 15 element phases

摘要

The reaction between equimolar quantities of BiCl_3 and the silylphosphine P(SiMe_3)_3 in toluene or THF (tetrahydrofuran) solution affords a black precipitate with the composition of bismuth phosphide, BiP, which has been examined by EDXA, SEM, XPS, powder XRD, solid-state ~31P NMR spectroscopy, and elemental analysis.
