Ba Co Co Tc
BaTcCo2 crystallizes in the triclinic P1 space group. Ba(1) is bonded in a distorted single-bond geometry to one Co(1) and four equivalent Co(2) atoms. The Ba(1)-Co(1) bond length is 2.13 Å. There are a spread of Ba(1)-Co(2) bond distances ranging from 2.81-3.21 Å. Tc(1) is bonded in a single-bond geometry to one Co(1) and one Co(2) atom. The Tc(1)-Co(1) bond length is 0.37 Å. The Tc(1)-Co(2) bond length is 2.84 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted bent 150 degrees geometry to one Ba(1), one Tc(1), and one Co(2) atom. The Co(1)-Co(2) bond length is 2.64 Å. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), one Tc(1), one Co(1), and two equivalent Co(2) atoms. Both Co(2)-Co(2) bond lengths are 2.99 Å.
