Co Co Tc Bi
TcCo2Bi crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a 3-coordinate geometry to two equivalent Co(1) and four equivalent Bi(1) atoms. There is one shorter (3.16 Å) and one longer (3.23 Å) Tc(1)-Co(1) bond length. There are a spread of Tc(1)-Bi(1) bond distances ranging from 2.05-2.58 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 14-coordinate geometry to two equivalent Tc(1), four equivalent Co(1), four equivalent Co(2), and four equivalent Bi(1) atoms. All Co(1)-Co(1) bond lengths are 3.12 Å. There are a spread of Co(1)-Co(2) bond distances ranging from 2.52-2.96 Å. There are a spread of Co(1)-Bi(1) bond distances ranging from 3.15-3.51 Å. In the second Co site, Co(2) is bonded in a 1-coordinate geometry to four equivalent Co(1) and one Bi(1) atom. The Co(2)-Bi(1) bond length is 2.30 Å. Bi(1) is bonded in a 5-coordinate geometry to four equivalent Tc(1), one Co(2), and four equivalent Co(1) atoms.
