The material structure described by KCd3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded in a distorted body-centered cubic geometry to six equivalent Cd(2) and eight equivalent Cd(1) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to four equivalent K(1) and four equivalent Cd(2) atoms to form a mixture of distorted corner, face, and edge-sharing CdK4Cd4 tetrahedra. In the second Cd site, Cd(2) is bonded in a 14-coordinate geometry to six equivalent K(1) and eight equivalent Cd(1) atoms. is represented by the CIF file [CIF]
