The material structure described by Na2Mg(SbO3)2 crystallizes in the trigonal R-3 space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share edges with six equivalent Sb(1)O6 octahedra. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share edges with three equivalent Mg(1)O6 octahedra and edges with three equivalent Sb(1)O6 octahedra. O(1) is bonded to two equivalent Na(1), one Mg(1), and two equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing ONa2MgSb2 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
