RuAg2Sn is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuAg2Sn clusters. Ru(1) is bonded in a 3-coordinate geometry to two equivalent Ag(1) and one Sn(1) atom. Both Ru(1)-Ag(1) bond lengths are 1.96 Å. The Ru(1)-Sn(1) bond length is 1.86 Å. Ag(1) is bonded in a single-bond geometry to one Ru(1) and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 0.24 Å. Sn(1) is bonded in a distorted single-bond geometry to one Ru(1) atom.
