The material described by Pm2CuSn is Heusler structured and crystallizes in the tetragonal I4/mmm space group. Pm(1) is bonded in a body-centered cubic geometry to four equivalent Cu(1) and four equivalent Sn(1) atoms. Cu(1) is bonded in a body-centered cubic geometry to eight equivalent Pm(1) atoms. Sn(1) is bonded in a body-centered cubic geometry to eight equivalent Pm(1) atoms. is represented by the CIF file [CIF]
