Praseodymium arsenide is a binary inorganic compound of praseodymium and arsenic with the formula PrAs.
Praseodymium arsenide can be prepared by heating praseodymium and arsenic:
Praseodymium arsenide forms cubic crystals, space group F m3m, cell parameters a = 0.6009 nm, Z = 4, and structure like sodium chloride.[1][2][3][4] When heated, it decomposes into arsenic and Pr4As3.[2] At a pressure of 27 GPa, a phase transition to the tetragonal crystal system occurs.[5]
