Materials Data on K3As by Materials Project
Abstract
K3As is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a distorted single-bond geometry to four equivalent As3- atoms. There are one shorter (3.42 Å) and three longer (3.82 Å) K–As bond lengths. In the second K1+ site, K1+ is bonded in a trigonal planar geometry to three equivalent As3- atoms. All K–As bond lengths are 3.38 Å. As3- is bonded to eleven K1+ atoms to form a mixture of distorted edge and face-sharing AsK11 trigonal bipyramids.
