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.
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. All Mg(1)-O(1) bond lengths are 2.15 Å. Ag(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. All Ag(1)-O(1) bond lengths are 2.29 Å. Bi(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (2.27 Å) and three longer (2.31 Å) Bi(1)-O(1) bond lengths. 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.
