The crystal structure described by MgFeSbO4 crystallizes in the monoclinic P2 space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with four equivalent Fe(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with four equivalent Sb(1)O6 octahedra, and faces with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-42°. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted FeO6 octahedra that share corners with four equivalent Mg(1)O6 octahedra, corners with eight equivalent Sb(1)O6 octahedra, edges with two equivalent Fe(1)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-52°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with eight equivalent Fe(1)O6 octahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-52°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1), two equivalent Fe(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OMg2Fe2Sb square pyramids. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Fe(1), and two equivalent Sb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
