Ru2AgSn crystallizes in the monoclinic Cm space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Ru(2) and one Ag(1) atom. The Ru(1)-Ru(2) bond length is 2.71 Å. The Ru(1)-Ag(1) bond length is 2.21 Å. In the second Ru site, Ru(2) is bonded to one Ru(1), six equivalent Ru(2), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing RuSnRu7 hexagonal bipyramids. All Ru(2)-Ru(2) bond lengths are 2.99 Å. The Ru(2)-Sn(1) bond length is 3.09 Å. Ag(1) is bonded in a distorted linear geometry to one Ru(1) and one Sn(1) atom. The Ag(1)-Sn(1) bond length is 0.88 Å. Sn(1) is bonded in a single-bond geometry to one Ru(2) and one Ag(1) atom.
