Title: Materials Data on KMgAs by Materials Project

Abstract

KMgAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five equivalent As3- atoms. There are four shorter (3.48 Å) and one longer (3.54 Å) K–As bond lengths. Mg2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing MgAs4 tetrahedra. All Mg–As bond lengths are 2.74 Å. As3- is bonded in a 9-coordinate geometry to five equivalent K1+ and four equivalent Mg2+ atoms.
