The structure described by Th5Sn4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Th sites. In the first Th site, Th(1) is bonded in a 6-coordinate geometry to one Sn(3), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the second Th site, Th(2) is bonded in a 7-coordinate geometry to one Sn(2), two equivalent Sn(3), and four equivalent Sn(1) atoms. In the third Th site, Th(3) is bonded to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms to form distorted corner-sharing ThSn6 octahedra. The corner-sharing octahedral tilt angles range from 49-55°. There are three inequivalent Sn sites. In the first Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Th(1), two equivalent Th(3), four equivalent Th(2), and one Sn(2) atom. In the second Sn site, Sn(1) is bonded in a 8-coordinate geometry to one Th(3), three equivalent Th(1), and four equivalent Th(2) atoms. In the third Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Th(2), two equivalent Th(3), four equivalent Th(1), and one Sn(3) atom. is represented by the CIF file [CIF]
