ThSc2(RhB)12 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Th is bonded in a 12-coordinate geometry to twelve Rh and twelve B atoms. There are four shorter (3.00 Å) and eight longer (3.20 Å) Th–Rh bond lengths. There are a spread of Th–B bond distances ranging from 3.02–3.19 Å. There are three inequivalent Sc sites. In the first Sc site, Sc is bonded in a 12-coordinate geometry to twelve Rh and twelve B atoms. There are a spread of Sc–Rh bond distances ranging from 2.89–3.19 Å. There are a spread of Sc–B bond distances ranging from 3.00–3.17 Å. In the second Sc site, Sc is bonded in a 12-coordinate geometry to twelve Rh and twelve B atoms. There are four shorter (2.91 Å) and eight longer (3.16 Å) Sc–Rh bond lengths. There are eight shorter (3.02 Å) and four longer (3.16 Å) Sc–B bond lengths.
