Y Y Sn Ru
Y2RuSn crystallizes in the monoclinic Pm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to one Y(2), four equivalent Y(1), and two equivalent Sn(1) atoms. The Y(1)-Y(2) bond length is 2.38 Å. All Y(1)-Y(1) bond lengths are 3.43 Å. There is one shorter (3.15 Å) and one longer (3.51 Å) Y(1)-Sn(1) bond length. In the second Y site, Y(2) is bonded in a 3-coordinate geometry to one Y(1) and two equivalent Ru(1) atoms. There is one shorter (2.96 Å) and one longer (3.34 Å) Y(2)-Ru(1) bond length. Ru(1) is bonded in a single-bond geometry to two equivalent Y(2) and one Sn(1) atom. The Ru(1)-Sn(1) bond length is 0.21 Å. Sn(1) is bonded in a single-bond geometry to two equivalent Y(1) and one Ru(1) atom.
