Platinum diphosphide is a binary inorganic compound of platinum metal and phosphorus with the chemical formula PtP2.[1][2]
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:[3][4]
- 2 Pt + P4 → 2 PtP2
Also, by reducing platinum(II) acetylacetonate to platinum nanoparticles and reacting with trioctylphosphine at 370 °C.[5]
