Praseodymium antimonide

Praseodymium antimonide is a binary inorganic compound of praseodymium and antimony with the formula PrSb.

Preparation
Praseodymium antimonide can be prepared by heating praseodymium and antimony in a vacuum:


 * $$\mathsf{ Pr + Sb \ \xrightarrow{2170^oC}\ PrSb }$$

Physical properties
Praseodymium antimonide forms cubic crystals, space group Fm$\overline{3}$m, cell parameters a = 0.638 nm, Z = 4, and structure like sodium chloride.

The compound melts congruently at 2170 °C or 2161 °C. At a temperature of 1950 °C, a phase transition occurs in the crystals. At a pressure of 13 GPa, a phase transition also occurs.
