Y Sn Sn Pd
YPdSn2 crystallizes in the trigonal R3m space group. Y(1) is bonded in a 10-coordinate geometry to three equivalent Pd(1), three equivalent Sn(2), and four equivalent Sn(1) atoms. All Y(1)-Pd(1) bond lengths are 3.06 Å. All Y(1)-Sn(2) bond lengths are 3.05 Å. There is one shorter (2.49 Å) and three longer (3.38 Å) Y(1)-Sn(1) bond lengths. Pd(1) is bonded in a 10-coordinate geometry to three equivalent Y(1), three equivalent Sn(1), and four equivalent Sn(2) atoms. All Pd(1)-Sn(1) bond lengths are 3.05 Å. There is one shorter (2.49 Å) and three longer (3.38 Å) Pd(1)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to four equivalent Y(1), three equivalent Pd(1), and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 2.49 Å. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to three equivalent Y(1), four equivalent Pd(1), and one Sn(1) atom.
