Ca Co Tc Tc
CaTc2Co crystallizes in the monoclinic Cm space group. Ca(1) is bonded in a 9-coordinate geometry to one Tc(1), four equivalent Tc(2), and four equivalent Co(1) atoms. The Ca(1)-Tc(1) bond length is 3.00 Å. There are a spread of Ca(1)-Tc(2) bond distances ranging from 2.82-3.22 Å. There are a spread of Ca(1)-Co(1) bond distances ranging from 2.05-2.57 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 13-coordinate geometry to one Ca(1), four equivalent Tc(1), four equivalent Tc(2), and four equivalent Co(1) atoms. All Tc(1)-Tc(1) bond lengths are 3.12 Å. There are a spread of Tc(1)-Tc(2) bond distances ranging from 2.79-3.19 Å. There are a spread of Tc(1)-Co(1) bond distances ranging from 3.03-3.41 Å. In the second Tc site, Tc(2) is bonded in a 13-coordinate geometry to four equivalent Ca(1), four equivalent Tc(1), four equivalent Tc(2), and one Co(1) atom. All Tc(2)-Tc(2) bond lengths are 3.12 Å. The Tc(2)-Co(1) bond length is 2.72 Å. Co(1) is bonded in a 4-coordinate geometry to four equivalent Ca(1), one Tc(2), and four equivalent Tc(1) atoms.
