Ho2Au2In crystallizes in the tetragonal P4/mbm space group. Ho(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. Au(1) is bonded in a 9-coordinate geometry to six equivalent Ho(1), one Au(1), and two equivalent In(1) atoms. In(1) is bonded to eight equivalent Ho(1) and four equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing InHo8Au4 cuboctahedra.
Ho2Au2In crystallizes in the tetragonal P4/mbm space group. Ho(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent In(1) atoms. There are two shorter (2.91 Å) and four longer (3.01 Å) Ho(1)-Au(1) bond lengths. All Ho(1)-In(1) bond lengths are 3.46 Å. Au(1) is bonded in a 9-coordinate geometry to six equivalent Ho(1), one Au(1), and two equivalent In(1) atoms. The Au(1)-Au(1) bond length is 2.86 Å. Both Au(1)-In(1) bond lengths are 3.09 Å. In(1) is bonded to eight equivalent Ho(1) and four equivalent Au(1) atoms to form a mixture of distorted face and corner-sharing InHo8Au4 cuboctahedra.
