Materials Data on Ho2Pt by Materials Project
Ho2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded to four equivalent Pt atoms to form a mixture of edge and corner-sharing HoPt4 tetrahedra. There are a spread of Ho–Pt bond distances ranging from 2.88–2.95 Å. In the second Ho site, Ho is bonded in a 3-coordinate geometry to three equivalent Pt atoms. There are one shorter (2.82 Å) and two longer (3.06 Å) Ho–Pt bond lengths. Pt is bonded in a 7-coordinate geometry to seven Ho atoms.
