Title: Materials Data on KAgSe by Materials Project

Abstract

KAgSe 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 four equivalent Ag1+ and five equivalent Se2- atoms. All K–Ag bond lengths are 3.47 Å. There are four shorter (3.36 Å) and one longer (3.48 Å) K–Se bond lengths. Ag1+ is bonded to four equivalent K1+ and four equivalent Se2- atoms to form a mixture of distorted edge and face-sharing AgK4Se4 tetrahedra. All Ag–Se bond lengths are 2.83 Å. Se2- is bonded in a 9-coordinate geometry to five equivalent K1+ and four equivalent Ag1+ atoms.
