CrZn2SbO6 crystallizes in the monoclinic P2_1/m space group. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CrO6 octahedra that share corners with two equivalent Cr(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and corners with four equivalent Zn(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 41-44°. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a rectangular see-saw-like geometry to one O(3), one O(4), and two equivalent O(1) atoms.
