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:

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]
