ReRu2Sn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReRu2Sn clusters. Re(1) is bonded in a 3-coordinate geometry to two equivalent Ru(1) and one Sn(1) atom. Both Re(1)-Ru(1) bond lengths are 0.87 Å. The Re(1)-Sn(1) bond length is 0.58 Å. Ru(1) is bonded in a 3-coordinate geometry to one Re(1), one Ru(1), and one Sn(1) atom. The Ru(1)-Ru(1) bond length is 0.58 Å. The Ru(1)-Sn(1) bond length is 0.87 Å. Sn(1) is bonded in a distorted single-bond geometry to one Re(1) and two equivalent Ru(1) atoms.
