La Y Y Ru
LaY2Ru crystallizes in the monoclinic Cm space group. La(1) is bonded in a distorted single-bond geometry to one Y(1) and one Y(2) atom. The La(1)-Y(1) bond length is 3.91 Å. The La(1)-Y(2) bond length is 1.40 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 6-coordinate geometry to one La(1), four equivalent Y(1), and one Ru(1) atom. All Y(1)-Y(1) bond lengths are 3.49 Å. The Y(1)-Ru(1) bond length is 3.48 Å. In the second Y site, Y(2) is bonded in a distorted bent 120 degrees geometry to one La(1) and one Ru(1) atom. The Y(2)-Ru(1) bond length is 1.56 Å. Ru(1) is bonded in a single-bond geometry to one Y(1) and one Y(2) atom.
