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:

${\displaystyle {\mathsf {Pr+Sb\ {\xrightarrow {2170^{o}C}}\ PrSb}}}$

Physical properties

Praseodymium antimonide forms cubic crystals, space group Fm3m, cell parameters a = 0.638 nm, Z = 4, and structure like sodium chloride. ^{[1] [2] [3]}

The compound melts congruently at 2170 °C ^[1] or 2161 °C. ^[2] At a temperature of 1950 °C, a phase transition occurs in the crystals. At a pressure of 13 GPa, a phase transition also occurs. ^[4]
