The material structure described by PrMgSn crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded to four equivalent Sn(1) atoms to form distorted edge-sharing MgSn4 cuboctahedra. Pr(1) is bonded in a 5-coordinate geometry to five equivalent Sn(1) atoms. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1) and five equivalent Pr(1) atoms. is represented by the CIF card [CIF]
