Ho2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. Au(1) is bonded in a 8-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and two equivalent Sn(1) atoms. Sn(1) is bonded to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing SnHo8Au4 cuboctahedra.
Ho2Au2Sn crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. There are two shorter (2.93 Å) and four longer (3.08 Å) Ho(1)-Au(1) bond lengths. All Ho(1)-Sn(1) bond lengths are 3.52 Å. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Sn(1) atoms. There are two shorter (2.96 Å) and four longer (3.01 Å) Ho(2)-Au(1) bond lengths. All Ho(2)-Sn(1) bond lengths are 3.45 Å. Au(1) is bonded in a 8-coordinate geometry to three equivalent Ho(1), three equivalent Ho(2), and two equivalent Sn(1) atoms. Both Au(1)-Sn(1) bond lengths are 3.13 Å. Sn(1) is bonded to four equivalent Ho(1), four equivalent Ho(2), and four equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing SnHo8Au4 cuboctahedra.
