Molybdenum phosphide is an inorganic chemical compound of molybdenum from the group of phosphides . In addition to this, at least two further molybdenum phosphides are known with trimolybdenum phosphide Mo ₃ P and molybdenum diphosphide MoP ₂ .

Extraction and presentation

Molybdenum phosphide can be obtained by reacting molybdenum with phosphorus . Wöhler and Rautenberg obtained the compound by reacting molybdenum trioxide with phosphoric acid in a carbon crucible.
