Y Hg Hg Ru
YRuHg2 crystallizes in the monoclinic Cm space group. Y(1) is bonded in a single-bond geometry to one Ru(1) and one Hg(1) atom. The Y(1)-Ru(1) bond length is 2.63 Å. The Y(1)-Hg(1) bond length is 0.84 Å. Ru(1) is bonded in a single-bond geometry to one Y(1) and one Hg(2) atom. The Ru(1)-Hg(2) bond length is 3.47 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a single-bond geometry to one Y(1) and one Hg(2) atom. The Hg(1)-Hg(2) bond length is 2.76 Å. In the second Hg site, Hg(2) is bonded to one Ru(1), one Hg(1), and six equivalent Hg(2) atoms to form a mixture of distorted corner and edge-sharing HgHg7Ru hexagonal bipyramids. All Hg(2)-Hg(2) bond lengths are 3.26 Å.
