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.
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. There are three shorter (2.08 Å) and three longer (2.51 Å) Cu(1)-O(1) bond lengths. As(1) is bonded to six equivalent O(1) atoms to form edge-sharing AsO6 octahedra. There are three shorter (1.90 Å) and three longer (1.93 Å) As(1)-O(1) bond lengths. O(1) is bonded in a 4-coordinate geometry to two equivalent Cu(1) and two equivalent As(1) atoms.
