The material described by SrMg(SbO3)2 is Ilmenite-derived structured and crystallizes in the trigonal P-31m space group. Sr(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 one Sr(1), one Mg(1), and two equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing OSrMgSb2 trigonal pyramids. is represented by the CIF card [CIF]
