PdZn2Sn crystallizes in the trigonal R3m space group. Pd(1) is bonded in a distorted q6 geometry to three equivalent Zn(2), four equivalent Zn(1), and three equivalent Sn(1) atoms. All Pd(1)-Zn(2) bond lengths are 2.70 Å. There are three shorter (2.75 Å) and one longer (3.18 Å) Pd(1)-Zn(1) bond length. All Pd(1)-Sn(1) bond lengths are 2.70 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to four equivalent Pd(1), one Zn(2), and three equivalent Sn(1) atoms. The Zn(1)-Zn(2) bond length is 0.91 Å. All Zn(1)-Sn(1) bond lengths are 2.70 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to three equivalent Pd(1), one Zn(1), and four equivalent Sn(1) atoms. There are three shorter (2.75 Å) and one longer (3.18 Å) Zn(2)-Sn(1) bond length. Sn(1) is bonded in a distorted q6 geometry to three equivalent Pd(1), three equivalent Zn(1), and four equivalent Zn(2) atoms.
