The material structure described by Ho2Co7B3 crystallizes in the hexagonal P6/mmm space group. There are three inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 20-coordinate geometry to two equivalent Ho(2), twelve equivalent Co(2), and six equivalent B(2) atoms. In the second Ho site, Ho(2) is bonded in a 18-coordinate geometry to one Ho(1), six equivalent Co(2), six equivalent Co(3), and six equivalent B(1) atoms. In the third Ho site, Ho(3) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Ho(3) and six equivalent Co(3) atoms. In the second Co site, Co(2) is bonded in a distorted square co-planar geometry to two equivalent Ho(1), two equivalent Ho(2), two equivalent B(1), and two equivalent B(2) atoms. In the third Co site, Co(3) is bonded in a distorted L-shaped geometry to two equivalent Ho(2), two equivalent Co(1), and two equivalent B(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to three equivalent Ho(2), three equivalent Co(2), and three equivalent Co(3) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to three equivalent Ho(1) and six equivalent Co(2) atoms. is represented by the CIF file [CIF]
