Th2Sc(B2C)3 crystallizes in the hexagonal P6/mmm space group. Th(1) is bonded in a 6-coordinate geometry to six equivalent C(1) atoms. Sc(1) is bonded to twelve equivalent B(1) atoms to form face-sharing ScB12 cuboctahedra. B(1) is bonded in a distorted single-bond geometry to two equivalent Sc(1) and one C(1) atom. C(1) is bonded in a distorted linear geometry to four equivalent Th(1) and two equivalent B(1) atoms.
