KCd2Zn crystallizes in the monoclinic Cm space group. K(1) is bonded in a 11-coordinate geometry to eight equivalent Cd(1) and three equivalent Zn(1) atoms. There are a spread of K(1)-Cd(1) bond distances ranging from 3.12-3.84 Å. There is one shorter (2.67 Å) and two longer (3.46 Å) K(1)-Zn(1) bond lengths. Cd(1) is bonded in a 9-coordinate geometry to four equivalent K(1), three equivalent Cd(1), and two equivalent Zn(1) atoms. There is one shorter (2.67 Å) and two longer (3.46 Å) Cd(1)-Cd(1) bond lengths. There is one shorter (3.12 Å) and one longer (3.14 Å) Cd(1)-Zn(1) bond length. Zn(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and four equivalent Cd(1) atoms.
