The material structure described by Mg2MnSbO6 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), and four equivalent O(3) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), and four equivalent O(4) atoms. Mn(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-46°. Sb(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-50°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mg(2), and two equivalent Sb(1) atoms to form OMg2Sb2 tetrahedra that share corners with two equivalent O(1)Mg2Sb2 tetrahedra and corners with two equivalent O(2)Mg2Mn2 trigonal pyramids. In the second O site, O(2) is bonded to one Mg(1), one Mg(2), and two equivalent Mn(1) atoms to form distorted OMg2Mn2 trigonal pyramids that share corners with two equivalent O(1)Mg2Sb2 tetrahedra and corners with two equivalent O(2)Mg2Mn2 trigonal pyramids. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Mg(1), one Mn(1), and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Mg(2), one Mn(1), and one Sb(1) atom. is represented by the CIF file [CIF]
