K2Cd(CN)4 crystallizes in the cubic Fd-3m space group. K(1) is bonded to six equivalent N(1) atoms to form distorted edge-sharing KN6 octahedra. Cd(1) is bonded to four equivalent C(1) atoms to form CdC4 tetrahedra that share corners with four equivalent N(1)K3C tetrahedra. C(1) is bonded in a linear geometry to one Cd(1) and one N(1) atom. N(1) is bonded to three equivalent K(1) and one C(1) atom to form distorted NK3C tetrahedra that share  a cornercorner with one Cd(1)C4 tetrahedra, corners with nine equivalent N(1)K3C tetrahedra, and edges with three equivalent N(1)K3C tetrahedra.
