ThAu3 crystallizes in the hexagonal P6_3/mmc space group. Th(1) is bonded to twelve equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing ThAu12 cuboctahedra. Au(1) is bonded in a 10-coordinate geometry to four equivalent Th(1) and six equivalent Au(1) atoms.
ThAu3 crystallizes in the hexagonal P6_3/mmc space group. Th(1) is bonded to twelve equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing ThAu12 cuboctahedra. There are six shorter (3.11 Å) and six longer (3.28 Å) Th(1)-Au(1) bond lengths. Au(1) is bonded in a 10-coordinate geometry to four equivalent Th(1) and six equivalent Au(1) atoms. There are four shorter (2.93 Å) and two longer (3.03 Å) Au(1)-Au(1) bond lengths.
