Pt2CdTl is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pt2CdTl clusters. Pt(1) is bonded in an L-shaped geometry to one Cd(1) and one Tl(1) atom. The Pt(1)-Cd(1) bond length is 0.60 Å. The Pt(1)-Tl(1) bond length is 0.60 Å. Cd(1) is bonded in an L-shaped geometry to two equivalent Pt(1) atoms. Tl(1) is bonded in an L-shaped geometry to two equivalent Pt(1) atoms.
