CuSb2O6 is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1/c space group. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CuO6 octahedra that share corners with eight equivalent Sb(1)O6 octahedra and edges with two equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with four equivalent Cu(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra,  an edgeedge with one Cu(1)O6 octahedra, and  an edgeedge with one Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent Sb(1) atoms.
