Synthesis
editMolybdenum diphosphide can be obtained by heating molybdenum with red phosphorus in a closed tube at 550 °C:
- Mo + 2P → MoP2
Properties
editMolybdenum 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
editMolybdenum diphosphide can be used as a catalyst.[5]
