MnSb2O6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 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 52-53°. 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 Mn(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra,  an edgeedge with one Mn(1)O6 octahedra, and  an edgeedge with one Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-53°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Sb(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to one Mn(1) and two equivalent Sb(1) atoms.
