Cr(SbO3)2 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CrO6 octahedra that share corners with twelve equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and edges with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms.

Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CrO6 octahedra that share corners with twelve equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. Both Cr(1)-O(2) bond lengths are 2.13 Å. All Cr(1)-O(1) bond lengths are 2.33 Å. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and edges with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. Both Sb(1)-O(2) bond lengths are 2.04 Å. There are two shorter (2.01 Å) and two longer (2.02 Å) Sb(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms.
