YRu2 crystallizes in the triclinic P1 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted single-bond geometry to one Ru(3) and one Ru(4) atom. The Y(1)-Ru(3) bond length is 2.13 Å. The Y(1)-Ru(4) bond length is 0.99 Å. In the second Y site, Y(2) is bonded in a distorted water-like geometry to one Ru(1), one Ru(4), and two equivalent Ru(2) atoms. The Y(2)-Ru(1) bond length is 2.17 Å. The Y(2)-Ru(4) bond length is 2.17 Å. There is one shorter (2.99 Å) and one longer (3.33 Å) Y(2)-Ru(2) bond length. There are four inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Y(2) and three equivalent Ru(2) atoms. There are a spread of Ru(1)-Ru(2) bond distances ranging from 1.92-3.49 Å. In the second Ru site, Ru(2) is bonded in a 9-coordinate geometry to two equivalent Y(2), two equivalent Ru(2), two equivalent Ru(3), and three equivalent Ru(1) atoms. Both Ru(2)-Ru(2) bond lengths are 2.93 Å. There is one shorter (2.25 Å) and one longer (3.07 Å) Ru(2)-Ru(3) bond length. In the third Ru site, Ru(3) is bonded in a 3-coordinate geometry to one Y(1), one Ru(4), and two equivalent Ru(2) atoms. The Ru(3)-Ru(4) bond length is 1.92 Å. In the fourth Ru site, Ru(4) is bonded in a distorted single-bond geometry to one Y(1), one Y(2), and one Ru(3) atom.
