Osmium diphosphide is a binary inorganic compoundofosmium metal and phosphorus with the chemical formula OsP₂.

Synthesis[edit]

Osmium diphosphide can be obtained by fusion of stoichiometric amounts of osmium and red phosphorus at 500-1000 °C:

Os + 2P → OsP₂

Osmium diphosphide forms black crystals of orthorhombic crystal system with space group P nnm.^[1]

Osmium diphosphide can be used as a semiconductor.^[2]
