The material described by Th4H15 crystallizes in the cubic I-43d space group. Th(1) is bonded to three equivalent H(2) and nine equivalent H(1) atoms to form a mixture of face and edge-sharing ThH12 cuboctahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a trigonal planar geometry to three equivalent Th(1) atoms. In the second H site, H(2) is bonded to four equivalent Th(1) atoms to form corner-sharing HTh4 tetrahedra. is represented by the CIF file [CIF]
