K Tc Tc Bi
KTc2Bi crystallizes in the monoclinic Cm space group. K(1) is bonded in a 3-coordinate geometry to four equivalent Tc(1) and four equivalent Bi(1) atoms. There are a spread of K(1)-Tc(1) bond distances ranging from 3.79-4.20 Å. There are a spread of K(1)-Bi(1) bond distances ranging from 2.85-3.38 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 11-coordinate geometry to four equivalent K(1), three equivalent Tc(2), and four equivalent Tc(1) atoms. There is one shorter (3.24 Å) and two longer (3.48 Å) Tc(1)-Tc(2) bond lengths. All Tc(1)-Tc(1) bond lengths are 3.16 Å. In the second Tc site, Tc(2) is bonded in a 4-coordinate geometry to three equivalent Tc(1) and four equivalent Bi(1) atoms. There are a spread of Tc(2)-Bi(1) bond distances ranging from 2.25-2.89 Å. Bi(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Tc(2) atoms.
