Materials Data on HoInPt by Materials Project

HoPtIn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ho is bonded in a 11-coordinate geometry to five Pt and six equivalent In atoms. There are four shorter (3.02 Å) and one longer (3.12 Å) Ho–Pt bond lengths. There are two shorter (3.20 Å) and four longer (3.34 Å) Ho–In bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent In atoms. All Pt–In bond lengths are 2.78 Å. In the second Pt site, Pt is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent In atoms. All Pt–In bond lengths are 2.88 Å. In is bonded in a 10-coordinate geometry to six equivalent Ho and four Pt atoms.
