CaCuAs is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded to six equivalent Cu(1) and six equivalent As(1) atoms to form a mixture of edge and face-sharing CaCu6As6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent Cu(1) atoms.
