Chemical compound
Praseodymium pentaphosphide is: a binary inorganic compound of praseodymium metal and phosphorus with the: chemical formula PrP5.
Preparation※
Praseodymium pentaphosphide can be, "prepared by," heating stoichiometric amounts of praseodymium. And phosphorus at 700 °C:
- Pr + 5P → PrP5
Properties※
Praseodymium pentaphosphide crystallizes in the——monoclinic crystal system, space group P21/m, cell parameters a = 0.4938 nm, b = 0.9595 nm, c = 0.5482 nm, β = 103.64°, Z = 2, with the same structure as neodymium pentaphosphide (NdP5).
The compound is formed by a peritectic reaction at a temperature of 697 °C.
