TcRuSn2 crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a 2-coordinate geometry to one Ru(1) and four equivalent Sn(1) atoms. The Tc(1)-Ru(1) bond length is 1.62 Å. There are a spread of Tc(1)-Sn(1) bond distances ranging from 1.90-2.95 Å. Ru(1) is bonded in a single-bond geometry to one Tc(1) and one Sn(2) atom. The Ru(1)-Sn(2) bond length is 2.95 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to four equivalent Tc(1) and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 1.72 Å. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Ru(1) and one Sn(1) atom.
