Mn Mn Tc Sn
TcMn2Sn crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a single-bond geometry to four equivalent Mn(2) and one Sn(1) atom. There are a spread of Tc(1)-Mn(2) bond distances ranging from 2.74-2.80 Å. The Tc(1)-Sn(1) bond length is 0.45 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 9-coordinate geometry to one Mn(2), four equivalent Mn(1), and four equivalent Sn(1) atoms. The Mn(1)-Mn(2) bond length is 1.71 Å. All Mn(1)-Mn(1) bond lengths are 3.02 Å. There are a spread of Mn(1)-Sn(1) bond distances ranging from 3.05-3.10 Å. In the second Mn site, Mn(2) is bonded in a 5-coordinate geometry to four equivalent Tc(1) and one Mn(1) atom. Sn(1) is bonded in a single-bond geometry to one Tc(1) and four equivalent Mn(1) atoms.
