NaPd2Sn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaPd2Sn clusters. Na(1) is bonded in a single-bond geometry to one Pd(2) atom. The Na(1)-Pd(2) bond length is 0.05 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Sn(1) atom. The Pd(1)-Sn(1) bond length is 0.81 Å. In the second Pd site, Pd(2) is bonded in a single-bond geometry to one Na(1) and one Sn(1) atom. The Pd(2)-Sn(1) bond length is 1.24 Å. Sn(1) is bonded in a bent 120 degrees geometry to one Pd(1) and one Pd(2) atom.
