PdSn4 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PdSn4 clusters. Pd(1) is bonded in a 3-coordinate geometry to one Sn(2) and two equivalent Sn(1) atoms. The Pd(1)-Sn(2) bond length is 2.07 Å. Both Pd(1)-Sn(1) bond lengths are 0.45 Å. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to one Pd(1) and one Sn(1) atom. The Sn(1)-Sn(1) bond length is 0.47 Å. In the second Sn site, Sn(2) is bonded in a linear geometry to one Pd(1) and one Sn(3) atom. The Sn(2)-Sn(3) bond length is 0.93 Å. In the third Sn site, Sn(3) is bonded in a single-bond geometry to one Sn(2) atom.
