The crystal structure described by CuAsO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Cu(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. As(1) is bonded to six equivalent O(1) atoms to form edge-sharing AsO6 octahedra. O(1) is bonded in a 4-coordinate geometry to two equivalent Cu(1) and two equivalent As(1) atoms. is represented by the CIF file [CIF]
