HoCo3B2 crystallizes in the hexagonal P6/mmm space group. Ho(1) is bonded in a 20-coordinate geometry to two equivalent Ho(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 Ho(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Ho(1) and six equivalent Co(1) atoms.
