NaPdCl2 crystallizes in the monoclinic Cm space group. Na(1) is bonded in a distorted single-bond geometry to one Pd(1), one Cl(1), and three equivalent Cl(2) atoms. The Na(1)-Pd(1) bond length is 2.71 Å. The Na(1)-Cl(1) bond length is 1.49 Å. There is one shorter (2.24 Å) and two longer (3.09 Å) Na(1)-Cl(2) bond lengths. Pd(1) is bonded in a 3-coordinate geometry to one Na(1), one Cl(1), and one Cl(2) atom. The Pd(1)-Cl(1) bond length is 2.79 Å. The Pd(1)-Cl(2) bond length is 2.79 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Na(1), one Pd(1), and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 2.04 Å. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to three equivalent Na(1), one Pd(1), and one Cl(1) atom.
