The compound described by K is alpha structured and crystallizes in the cubic I-43m space group. The structure consists of two 7440-09-7 atoms inside a K framework. In the K framework, there are three inequivalent K sites. In the first K site, K(2) is bonded in a trigonal non-coplanar geometry to three equivalent K(4) atoms. In the second K site, K(3) is bonded in a 6-coordinate geometry to three equivalent K(3) and five equivalent K(4) atoms. In the third K site, K(4) is bonded in a 8-coordinate geometry to one K(2), two equivalent K(4), and five equivalent K(3) atoms. is represented by the CIF file [CIF]
