Yb2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to four equivalent Pt(1) atoms to form a mixture of distorted corner and edge-sharing YbPt4 tetrahedra. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms.

In the first Yb site, Yb(1) is bonded to four equivalent Pt(1) atoms to form a mixture of distorted corner and edge-sharing YbPt4 tetrahedra. There are a spread of Yb(1)-Pt(1) bond distances ranging from 2.83-2.92 Å. In the second Yb site, Yb(2) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms. There are a spread of Yb(2)-Pt(1) bond distances ranging from 3.04-3.29 Å. Pt(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1) and five equivalent Yb(2) atoms.
