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.
