TbCo3B2 crystallizes in the hexagonal P6/mmm space group. Tb(1) is bonded in a 20-coordinate geometry to two equivalent Tb(1), twelve equivalent Co(1), and six equivalent B(1) atoms. Co(1) is bonded in a distorted square co-planar geometry to four equivalent Tb(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Tb(1) and six equivalent Co(1) atoms.
