The material described by Na2Mg(SbO3)2 crystallizes in the trigonal R-3 space group. Na(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 37°. Sb(1) is bonded to six equivalent O(1) atoms to form distorted SbO6 octahedra that share corners with three equivalent Mg(1)O6 octahedra, edges with three equivalent Sb(1)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 37°. O(1) is bonded in a 4-coordinate geometry to one Na(1), one Mg(1), and two equivalent Sb(1) atoms. is represented by the CIF card [CIF]
