Praseodymium monoselenide

Praseodymium monoselenide is a compound with the chemical formula PrSe. It forms crystals.

Preparation

Praseodymium monoselenide can be prepared by directly reacting praseodymium and selenium at 2100 °C:

Pr + Se → PrSe

The temperature at which selenium and praseodymium start to react when they come into contact is 620 K.

Properties

Praseodymium monoselenide forms cubic crystals, space group Fm3m, unit cell parameters a = 0.5741 nm, Z = 4, and a structure similar to that of sodium chloride.

The compound melts congruently at 2100 °C.
