Molybdenum diphosphide is a binary inorganic compound of molybdenum metal and phosphorus with the chemical formula MoP₂.^[1][2]

Synthesis

Molybdenum diphosphide can be obtained by heating molybdenum with red phosphorus in a closed tube at 550 °C:

Mo + 2P → MoP₂

Properties

Molybdenum diphosphide forms black crystals of orthorhombic crystal system with space group A2₁am.^[3][4] It is insoluble in water. It decomposes when heated, releasing molybdenum monophosphide and white phosphorus:

4MoP₂ → 4MoP + P₄

Uses

Molybdenum diphosphide can be used as a catalyst.^[5]
