HoNiSn crystallizes in the hexagonal P-62m space group. Ho(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent Sn(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Sn(1) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Ho(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Ho(1), two equivalent Ni(1), and two equivalent Ni(2) atoms.
HoNiSn crystallizes in the hexagonal P-62m space group. Ho(1) is bonded in a 11-coordinate geometry to one Ni(1), four equivalent Ni(2), and six equivalent Sn(1) atoms. The Ho(1)-Ni(1) bond length is 2.94 Å. All Ho(1)-Ni(2) bond lengths are 2.93 Å. There are two shorter (3.11 Å) and four longer (3.23 Å) Ho(1)-Sn(1) bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Sn(1) atoms. All Ni(1)-Sn(1) bond lengths are 2.69 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to six equivalent Ho(1) and three equivalent Sn(1) atoms. All Ni(2)-Sn(1) bond lengths are 2.72 Å.
