HoPtIn crystallizes in the hexagonal P-62m space group. Ho(1) is bonded in a 11-coordinate geometry to one Pt(1), four equivalent Pt(2), and six equivalent In(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent In(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to six equivalent Ho(1) and three equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Ho(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
HoPtIn crystallizes in the hexagonal P-62m space group. Ho(1) is bonded in a 11-coordinate geometry to one Pt(1), four equivalent Pt(2), and six equivalent In(1) atoms. The Ho(1)-Pt(1) bond length is 3.09 Å. All Ho(1)-Pt(2) bond lengths are 3.00 Å. There are two shorter (3.17 Å) and four longer (3.32 Å) Ho(1)-In(1) bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent In(1) atoms. All Pt(1)-In(1) bond lengths are 2.76 Å. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to six equivalent Ho(1) and three equivalent In(1) atoms. All Pt(2)-In(1) bond lengths are 2.85 Å. In(1) is bonded in a 10-coordinate geometry to six equivalent Ho(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
