Platinum diphosphide is a binary inorganic compound of platinum metal and phosphorus with the chemical formula PtP2.[1][2]

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:[3][4]

Pt + 2P → PtP2

Also, by reducing platinum(II) acetylacetonate to platinum nanoparticles and reacting with trioctylphosphine at 370 °C.[5]

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[6] and catalyst.[7]
