The Materials Project

K3AuSe2 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to two equivalent Au1+ and four equivalent Se2- atoms. Both K–Au bond lengths are 3.57 Å. There are two shorter (3.36 Å) and two longer (3.39 Å) K–Se bond lengths. Au1+ is bonded in a body-centered cubic geometry to six equivalent K1+ and two equivalent Se2- atoms. Both Au–Se bond lengths are 2.46 Å. Se2- is bonded in a 7-coordinate geometry to six equivalent K1+ and one Au1+ atom.
