Ho2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing HoPt4 tetrahedra. In the second Ho site, Ho(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Ho(2) and four equivalent Ho(1) atoms.

In the first Ho site, Ho(1) is bonded to four equivalent Pt(1) atoms to form a mixture of corner and edge-sharing HoPt4 tetrahedra. There is one shorter (2.85 Å) and three longer (2.93 Å) Ho(1)-Pt(1) bond lengths. In the second Ho site, Ho(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. There is one shorter (2.80 Å) and two longer (3.03 Å) Ho(2)-Pt(1) bond lengths. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Ho(2) and four equivalent Ho(1) atoms.
