CuSb(MoO4)2 crystallizes in the monoclinic C2/c space group. Mo(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form distorted MoO6 octahedra that share corners with two equivalent Cu(1)O6 octahedra, corners with four equivalent Mo(1)O6 octahedra, and  an edgeedge with one Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-53°. Cu(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form CuO6 octahedra that share corners with four equivalent Mo(1)O6 octahedra, corners with four equivalent Cu(1)O6 octahedra, and edges with two equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-57°. Sb(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Mo(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Mo(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mo(1) and two equivalent Cu(1) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Mo(1) and two equivalent Sb(1) atoms.
