Samarium(III) arsenide is a binary inorganic compound of samarium and arsenic with the chemical formula SmAs.[1][2]

Synthesis

Samarium arsenide can be synthesised by heating of pure substances in vacuum:

Sm + As → SmAs

Physical properties

Samarium arsenide forms crystals of a cubic system,[3] space group Fm3m, cell parameters a = 0.5921 nm, Z = 4, of NaCl-structure.[4][5]

The compound melts congruently at 2257 °C.
