The material structure described by MgAg2(BiO3)2 crystallizes in the trigonal R-3 space group. Mg(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. Ag(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. O(1) is bonded to one Mg(1), one Ag(1), and two equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OMgAgBi2 tetrahedra. is represented by the CIF card [CIF]
