The crystal structure described by Ho3YC8 crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a distorted q4 geometry to one C(2), one C(4), four equivalent C(1), and four equivalent C(3) atoms. In the second Ho site, Ho(2) is bonded in a distorted q4 geometry to two equivalent C(3) and eight equivalent C(2) atoms. Y(1) is bonded in a distorted q4 geometry to two equivalent C(1) and eight equivalent C(4) atoms. There are four inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to four equivalent Ho(1), one Y(1), and one C(3) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to one Ho(1), four equivalent Ho(2), and one C(2) atom. In the third C site, C(3) is bonded in a 6-coordinate geometry to one Ho(2), four equivalent Ho(1), and one C(1) atom. In the fourth C site, C(4) is bonded in a 6-coordinate geometry to one Ho(1), four equivalent Y(1), and one C(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
