The material described by MgCo2(SbO4)2 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form MgO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra and corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-61°. Co(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. Sb(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Co(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded to one Mg(1), two equivalent Co(1), and one Sb(1) atom to form distorted OMgCo2Sb tetrahedra that share  a cornercorner with one O(2)MgCo2Sb tetrahedra, corners with two equivalent O(4)MgCoSb2 trigonal pyramids,  an edgeedge with one O(2)MgCo2Sb tetrahedra, and edges with two equivalent O(4)MgCoSb2 trigonal pyramids. In the third O site, O(3) is bonded in a distorted T-shaped geometry to two equivalent Co(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded to one Mg(1), one Co(1), and two equivalent Sb(1) atoms to form distorted OMgCoSb2 trigonal pyramids that share corners with two equivalent O(2)MgCo2Sb tetrahedra,  a cornercorner with one O(4)MgCoSb2 trigonal pyramid, edges with two equivalent O(2)MgCo2Sb tetrahedra, and  an edgeedge with one O(4)MgCoSb2 trigonal pyramid. is represented by the CIF file [CIF]
