Co Tc Tc Os
Tc2OsCo 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 Os(1) and one Co(1) atom. There are a spread of Tc(1)-Os(1) bond distances ranging from 1.98-2.50 Å. The Tc(1)-Co(1) bond length is 1.29 Å. In the second Tc site, Tc(2) is bonded in a 6-coordinate geometry to two equivalent Os(1) and four equivalent Co(1) atoms. There is one shorter (2.77 Å) and one longer (2.85 Å) Tc(2)-Os(1) bond length. There are a spread of Tc(2)-Co(1) bond distances ranging from 2.28-2.75 Å. Os(1) is bonded in a 5-coordinate geometry to two equivalent Tc(2) and four equivalent Tc(1) atoms. Co(1) is bonded in a distorted single-bond geometry to one Tc(1) and four equivalent Tc(2) atoms.
