The structure described by K2NaAs is Sodium arsenide-derived structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded in a 11-coordinate geometry to four equivalent K(1), three equivalent Na(1), and four equivalent As(1) atoms. Na(1) is bonded in a trigonal planar geometry to six equivalent K(1) and three equivalent As(1) atoms. As(1) is bonded in a 11-coordinate geometry to eight equivalent K(1) and three equivalent Na(1) atoms. is represented by the CIF file [CIF]
