K Tc Bi Bi
KTcBi2 crystallizes in the triclinic P1 space group. K(1) is bonded in a 5-coordinate geometry to two equivalent Tc(1), one Bi(2), and two equivalent Bi(1) atoms. There is one shorter (2.81 Å) and one longer (3.10 Å) K(1)-Tc(1) bond length. The K(1)-Bi(2) bond length is 3.15 Å. There is one shorter (2.52 Å) and one longer (3.13 Å) K(1)-Bi(1) bond length. Tc(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Bi(2) atom. The Tc(1)-Bi(2) bond length is 2.52 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Bi(2) atom. The Bi(1)-Bi(2) bond length is 1.49 Å. In the second Bi site, Bi(2) is bonded in a 3-coordinate geometry to one K(1), one Tc(1), and one Bi(1) atom.
