The crystal structure described by CeMgSn crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to four equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing MgSn4 tetrahedra. Ce(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 Ce(1) atoms. is represented by the CIF file [CIF]
