Title: Materials Data on K2NaAs by Materials Project

Abstract

K2NaAs crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four equivalent As3- atoms. There are one shorter (3.56 Å) and three longer (3.57 Å) K–As bond lengths. Na1+ is bonded in a trigonal planar geometry to three equivalent As3- atoms. All Na–As bond lengths are 3.11 Å. As3- is bonded in a 11-coordinate geometry to eight equivalent K1+ and three equivalent Na1+ atoms.
