The crystal structure described by NaCd3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Na(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 Na(1) and four equivalent Cd(2) atoms to form a mixture of distorted corner, face, and edge-sharing CdNa4Cd4 tetrahedra. In the second Cd site, Cd(2) is bonded in a 14-coordinate geometry to six equivalent Na(1) and eight equivalent Cd(1) atoms. is represented by the CIF card [CIF]
