The material structure described by K2Cs is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure consists of four 7440-46-2 atoms inside a K framework. In the K framework, there are two inequivalent K sites. In the first K site, K(2) is bonded in a distorted hexagonal planar geometry to six equivalent K(1) atoms. In the second K site, K(1) is bonded in a distorted hexagonal planar geometry to two equivalent K(2) and four equivalent K(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
