The material described by Cr(SbO3)2 is Hydrophilite-derived structured and crystallizes in the orthorhombic P2_12_12 space group. Cr(1) is bonded to two equivalent O(1) and four O(2,2) atoms to form CrO6 octahedra that share corners with eight Sb(1,1)O6 octahedra and edges with two Sb(1,1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-51°. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra,  an edgeedge with one Cr(1)O6 octahedra, and  an edgeedge with one Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 51°. In the second Sb site, Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra,  an edgeedge with one Cr(1)O6 octahedra, and  an edgeedge with one Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Cr(1) and two Sb(1,1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms. In the third O site, O(2) is bonded in a trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
