ThB12 crystallizes in the cubic Fm-3m space group. Th(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1) atoms. B(1) is bonded in a 7-coordinate geometry to two equivalent Th(1) and five equivalent B(1) atoms.
ThB12 crystallizes in the cubic Fm-3m space group. Th(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1) atoms. All Th(1)-B(1) bond lengths are 2.83 Å. B(1) is bonded in a 7-coordinate geometry to two equivalent Th(1) and five equivalent B(1) atoms. There is one shorter (1.75 Å) and four longer (1.81 Å) B(1)-B(1) bond lengths.
