The crystal structure described by K3Cd16 crystallizes in the tetragonal P4/nnc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent K(2), eight equivalent Cd(1), and eight equivalent Cd(2) atoms. In the second K site, K(2) is bonded in a 14-coordinate geometry to one K(1), one K(2), four equivalent Cd(2), and eight equivalent Cd(1) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 11-coordinate geometry to one K(1), two equivalent K(2), three equivalent Cd(1), and five equivalent Cd(2) atoms. In the second Cd site, Cd(2) is bonded in a 10-coordinate geometry to one K(1), one K(2), three equivalent Cd(2), and five equivalent Cd(1) atoms. is represented by the CIF file [CIF]
