MgMoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. Mo(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent Mo(1) atoms to form distorted corner-sharing OMg2Mo2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Mo(1) atoms.
MgMoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There is one shorter (2.04 Å) and one longer (2.10 Å) Mg(1)-O(1) bond length. Both Mg(1)-O(2) bond lengths are 2.06 Å. Mo(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 46°. Both Mo(1)-O(1) bond lengths are 2.13 Å. There are two shorter (2.02 Å) and two longer (2.08 Å) Mo(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent Mo(1) atoms to form distorted corner-sharing OMg2Mo2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Mo(1) atoms.
