KCd2Zn crystallizes in the triclinic P1 space group. K(1) is bonded in a 11-coordinate geometry to four equivalent Cd(1), four equivalent Cd(2), and three equivalent Zn(1) atoms. There are a spread of K(1)-Cd(1) bond distances ranging from 3.00-3.97 Å. There are a spread of K(1)-Cd(2) bond distances ranging from 3.20-3.81 Å. There are a spread of K(1)-Zn(1) bond distances ranging from 2.76-3.64 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Cd(2) atoms. There is one shorter (2.76 Å) and one longer (3.29 Å) Cd(1)-Cd(2) bond length. In the second Cd site, Cd(2) is bonded in a 8-coordinate geometry to four equivalent K(1), two equivalent Cd(1), and two equivalent Zn(1) atoms. There is one shorter (3.00 Å) and one longer (3.18 Å) Cd(2)-Zn(1) bond length. Zn(1) is bonded in a 1-coordinate geometry to three equivalent K(1) and two equivalent Cd(2) atoms.
