The crystal structure described by MgSb2O4 crystallizes in the tetragonal P4_2/mbc space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing MgO6 octahedra. Sb(1) is bonded in a distorted T-shaped geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Sb(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mg(1) and one Sb(1) atom. is represented by the CIF card [CIF]
