BaMgMoO3 crystallizes in the trigonal R3m space group. Ba(1) is bonded in a 3-coordinate geometry to nine equivalent O(1) atoms. Mg(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. Mo(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 6°. O(1) is bonded in a 6-coordinate geometry to three equivalent Ba(1), one Mg(1), and two equivalent Mo(1) atoms.
BaMgMoO3 crystallizes in the trigonal R3m space group. Ba(1) is bonded in a 3-coordinate geometry to nine equivalent O(1) atoms. There are three shorter (2.64 Å) and six longer (3.16 Å) Ba(1)-O(1) bond lengths. Mg(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. All Mg(1)-O(1) bond lengths are 1.97 Å. Mo(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are three shorter (2.23 Å) and three longer (2.38 Å) Mo(1)-O(1) bond lengths. O(1) is bonded in a 6-coordinate geometry to three equivalent Ba(1), one Mg(1), and two equivalent Mo(1) atoms.
