NaPdZn2 crystallizes in the trigonal R3m space group. Na(1) is bonded in a 2-coordinate geometry to one Pd(1), one Zn(1), and three equivalent Zn(2) atoms. The Na(1)-Pd(1) bond length is 2.10 Å. The Na(1)-Zn(1) bond length is 2.30 Å. All Na(1)-Zn(2) bond lengths are 2.71 Å. Pd(1) is bonded in a 2-coordinate geometry to one Na(1) and four equivalent Zn(2) atoms. There is one shorter (2.30 Å) and three longer (2.97 Å) Pd(1)-Zn(2) bond lengths. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 1-coordinate geometry to one Na(1) and three equivalent Zn(2) atoms. All Zn(1)-Zn(2) bond lengths are 2.71 Å. In the second Zn site, Zn(2) is bonded in a 10-coordinate geometry to three equivalent Na(1), four equivalent Pd(1), and three equivalent Zn(1) atoms.
