CuAs2O4 crystallizes in the tetragonal P4_2/mbc space group. Cu(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted edge-sharing CuO6 octahedra. As(1) is bonded in a distorted T-shaped geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Cu(1) and two equivalent As(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one As(1) atom.
CuAs2O4 crystallizes in the tetragonal P4_2/mbc space group. Cu(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted edge-sharing CuO6 octahedra. Both Cu(1)-O(2) bond lengths are 2.61 Å. All Cu(1)-O(1) bond lengths are 1.96 Å. As(1) is bonded in a distorted T-shaped geometry to one O(1) and two equivalent O(2) atoms. The As(1)-O(1) bond length is 1.81 Å. Both As(1)-O(2) bond lengths are 1.85 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Cu(1) and two equivalent As(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one As(1) atom.
