Materials Data on KCd13 by Materials Project
KCd13 crystallizes in the cubic Fm-3c space group. The structure is three-dimensional. K is bonded in a 1-coordinate geometry to twenty-four equivalent Cd atoms. All K–Cd bond lengths are 4.09 Å. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded in a 12-coordinate geometry to two equivalent K and ten Cd atoms. There are a spread of Cd–Cd bond distances ranging from 2.92–3.42 Å. In the second Cd site, Cd is bonded in a cuboctahedral geometry to twelve equivalent Cd atoms.
