Platinum diphosphide

Platinum diphosphide is a binary inorganic compound of platinum metal and phosphorus with the chemical formula PtP2.

Synthesis
Platinum diphosphide can be prepared by passing phosphorus vapors over spongy platinum or prolonged heating of platinum and phosphorus in a vacuum ampoule at 570 °C:
 * Pt + 2P -> PtP2

Also, by reducing platinum(II) acetylacetonate to platinum nanoparticles and reacting with trioctylphosphine at 370 °C.

Properties
Platinum diphosphide forms silvery-white crystals of cubic crystal system with the space group Pa3.

Uses
Platinum diphosphide can be used as a semiconductor and catalyst.
