Chemical compound

Molybdenum monophosphide is a binary inorganic compound of molybdenum metal and phosphorus with the chemical formula MoP.[1][2][3]

## Preparation[edit]

Molybdenum monophosphide can be obtained from electrolysis of molten molybdenum hexametaphosphate:[4]

4 Mo(PO3)6 → 4 MoP + 10 P2O5 \+ 9 O2

It can also be prepared from heating of a mixture of molybdenum and metaphosphoric acid in a carbon crucible:

2 Mo + 2 HPO3 \+ 5 C → 2 MoP + 5 CO + H2O

Other reactions are known too.[5][6]

## Properties[edit]

Molybdenum monophosphide forms black crystals of hexagonal crystal system with space group P6m2.[7] It is insoluble in water. Molybdenum monophosphide decomposes when heated in air:

4 MoP + 11 O2 → 4 MoO3 \+ 2 P2O5

## Uses[edit]

Molybdenum monophosphide can be used as a catalyst.[8][9]
