PtCd3 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PtCd3 clusters. Pt(1) is bonded in an L-shaped geometry to one Cd(2) and two equivalent Cd(1) atoms. The Pt(1)-Cd(2) bond length is 0.96 Å. Both Pt(1)-Cd(1) bond lengths are 0.71 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a distorted single-bond geometry to one Pt(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 0.71 Å. In the second Cd site, Cd(2) is bonded in a distorted L-shaped geometry to one Pt(1) and two equivalent Cd(1) atoms.
