OsPdSn2 crystallizes in the monoclinic Cm space group. Os(1) is bonded to six equivalent Os(1), one Pd(1), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing OsSnOs6Pd hexagonal bipyramids. All Os(1)-Os(1) bond lengths are 3.20 Å. The Os(1)-Pd(1) bond length is 2.81 Å. The Os(1)-Sn(1) bond length is 3.48 Å. Pd(1) is bonded in a single-bond geometry to one Os(1) and one Sn(2) atom. The Pd(1)-Sn(2) bond length is 0.67 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Os(1) and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.69 Å. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Pd(1) and one Sn(1) atom.
