KCd13 crystallizes in the cubic Fm-3c space group. K(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Cd(1) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to two equivalent K(1), one Cd(2), and nine equivalent Cd(1) atoms. In the second Cd site, Cd(2) is bonded in a cuboctahedral geometry to twelve equivalent Cd(1) atoms.
KCd13 crystallizes in the cubic Fm-3c space group. K(1) is bonded in a 24-coordinate geometry to twenty-four equivalent Cd(1) atoms. All K(1)-Cd(1) bond lengths are 4.02 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 12-coordinate geometry to two equivalent K(1), one Cd(2), and nine equivalent Cd(1) atoms. The Cd(1)-Cd(2) bond length is 3.01 Å. There are a spread of Cd(1)-Cd(1) bond distances ranging from 2.87-3.36 Å. In the second Cd site, Cd(2) is bonded in a cuboctahedral geometry to twelve equivalent Cd(1) atoms.
