TmRh3B2 crystallizes in the hexagonal P6/mmm space group. Tm(1) is bonded in a 20-coordinate geometry to two equivalent Tm(1), twelve equivalent Rh(1), and six equivalent B(1) atoms. Rh(1) is bonded in a distorted square co-planar geometry to four equivalent Tm(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Tm(1) and six equivalent Rh(1) atoms.
