The structure described by K2Mg(SbO3)2 crystallizes in the trigonal R-3 space group. K(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 in a 5-coordinate geometry to two equivalent K(1), one Mg(1), and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
