The material structure described by Cu4AsO6Cl crystallizes in the orthorhombic Pbcm space group. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent O(2), two equivalent O(3), and one Cl(1) atom to form CuClO4 square pyramids that share  a cornercorner with one Cu(1)ClO4 square pyramid, corners with two equivalent As(1)O4 tetrahedra, and edges with two equivalent Cu(1)ClO4 square pyramids. In the second Cu site, Cu(2) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. In the third Cu site, Cu(3) is bonded in a 4-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent Cl(1) atoms. As(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form AsO4 tetrahedra that share corners with four equivalent Cu(1)ClO4 square pyramids. There are three inequivalent O sites. In the first O site, O(2) is bonded to one Cu(2), one Cu(3), and two equivalent Cu(1) atoms to form distorted edge-sharing OCu4 tetrahedra. In the second O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Cu(1) and one As(1) atom. In the third O site, O(1) is bonded in a trigonal planar geometry to one Cu(2), one Cu(3), and one As(1) atom. Cl(1) is bonded in a 4-coordinate geometry to two equivalent Cu(1) and two equivalent Cu(3) atoms. is represented by the CIF card [CIF]
