KHgAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded to six equivalent Hg(1) and six equivalent As(1) atoms to form a mixture of face and edge-sharing KHg6As6 cuboctahedra. Hg(1) is bonded in a 9-coordinate geometry to six equivalent K(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent K(1) and three equivalent Hg(1) atoms.
