PtTl2 crystallizes in the tetragonal I4/mcm space group. Pt(1) is bonded to two equivalent Pt(1) and four equivalent Tl(1) atoms to form distorted corner-sharing PtTl4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 0-41°. Tl(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Pt(1) atoms.

The corner-sharing octahedral tilt angles range from 0-41°. Both Pt(1)-Pt(1) bond lengths are 2.82 Å. All Pt(1)-Tl(1) bond lengths are 2.78 Å. Tl(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Pt(1) atoms.
