K Cd Cd Bi
KCd2Bi crystallizes in the triclinic P1 space group. K(1) is bonded in a 2-coordinate geometry to two equivalent Cd(1), two equivalent Cd(2), and two equivalent Bi(1) atoms. There is one shorter (2.51 Å) and one longer (3.00 Å) K(1)-Cd(1) bond length. There is one shorter (2.45 Å) and one longer (2.95 Å) K(1)-Cd(2) bond length. There is one shorter (3.43 Å) and one longer (3.60 Å) K(1)-Bi(1) bond length. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to two equivalent K(1), one Cd(2), and one Bi(1) atom. The Cd(1)-Cd(2) bond length is 1.69 Å. The Cd(1)-Bi(1) bond length is 3.54 Å. In the second Cd site, Cd(2) is bonded in a 3-coordinate geometry to two equivalent K(1), one Cd(1), and one Bi(1) atom. The Cd(2)-Bi(1) bond length is 3.54 Å. Bi(1) is bonded to two equivalent K(1), one Cd(1), one Cd(2), and two equivalent Bi(1) atoms to form distorted corner-sharing BiK2Cd2Bi2 octahedra. The corner-sharing octahedra are not tilted. Both Bi(1)-Bi(1) bond lengths are 3.51 Å.
