Co Tc Tc Sn
Tc2CoSn crystallizes in the monoclinic Cm space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 5-coordinate geometry to four equivalent Tc(2), one Co(1), and four equivalent Sn(1) atoms. There are a spread of Tc(1)-Tc(2) bond distances ranging from 3.10-3.35 Å. The Tc(1)-Co(1) bond length is 2.38 Å. There are a spread of Tc(1)-Sn(1) bond distances ranging from 1.93-2.31 Å. In the second Tc site, Tc(2) is bonded in a 13-coordinate geometry to four equivalent Tc(1), four equivalent Tc(2), four equivalent Co(1), and one Sn(1) atom. All Tc(2)-Tc(2) bond lengths are 2.90 Å. There are a spread of Tc(2)-Co(1) bond distances ranging from 2.95-3.21 Å. The Tc(2)-Sn(1) bond length is 3.00 Å. Co(1) is bonded in a 13-coordinate geometry to one Tc(1), four equivalent Tc(2), four equivalent Co(1), and four equivalent Sn(1) atoms. All Co(1)-Co(1) bond lengths are 2.90 Å. There are a spread of Co(1)-Sn(1) bond distances ranging from 2.63-2.92 Å. Sn(1) is bonded in a 4-coordinate geometry to one Tc(2), four equivalent Tc(1), and four equivalent Co(1) atoms.
