PtIn crystallizes in the monoclinic C2/m space group. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to two equivalent In(2) and four equivalent In(3) atoms to form distorted edge-sharing PtIn6 octahedra. In the second Pt site, Pt(2) is bonded in a 6-coordinate geometry to one In(1), two equivalent In(3), and three equivalent In(2) atoms. In the third Pt site, Pt(3) is bonded in a 7-coordinate geometry to two equivalent In(1), two equivalent In(2), and three equivalent In(3) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 6-coordinate geometry to two equivalent Pt(2) and four equivalent Pt(3) atoms. In the second In site, In(2) is bonded in a 6-coordinate geometry to one Pt(1), two equivalent Pt(3), and three equivalent Pt(2) atoms. In the third In site, In(3) is bonded in a 7-coordinate geometry to two equivalent Pt(1), two equivalent Pt(2), and three equivalent Pt(3) atoms.

In the first Pt site, Pt(1) is bonded to two equivalent In(2) and four equivalent In(3) atoms to form distorted edge-sharing PtIn6 octahedra. Both Pt(1)-In(2) bond lengths are 2.81 Å. All Pt(1)-In(3) bond lengths are 2.80 Å. In the second Pt site, Pt(2) is bonded in a 6-coordinate geometry to one In(1), two equivalent In(3), and three equivalent In(2) atoms. The Pt(2)-In(1) bond length is 2.67 Å. Both Pt(2)-In(3) bond lengths are 2.78 Å. There is one shorter (2.70 Å) and two longer (2.85 Å) Pt(2)-In(2) bond lengths. In the third Pt site, Pt(3) is bonded in a 7-coordinate geometry to two equivalent In(1), two equivalent In(2), and three equivalent In(3) atoms. Both Pt(3)-In(1) bond lengths are 2.82 Å. There is one shorter (2.83 Å) and one longer (2.87 Å) Pt(3)-In(2) bond length. There are two shorter (2.79 Å) and one longer (2.96 Å) Pt(3)-In(3) bond length. There are three inequivalent In sites.
