Ti2Rh6B crystallizes in the cubic Fm-3m space group. Ti(1) is bonded to twelve equivalent Rh(1) atoms to form TiRh12 cuboctahedra that share corners with twelve equivalent Ti(1)Rh12 cuboctahedra, faces with six equivalent Ti(1)Rh12 cuboctahedra, and faces with four equivalent B(1)Rh6 octahedra. Rh(1) is bonded in a 1-coordinate geometry to four equivalent Ti(1) and one B(1) atom. B(1) is bonded to six equivalent Rh(1) atoms to form BRh6 octahedra that share faces with eight equivalent Ti(1)Rh12 cuboctahedra.
