SrMgMoO3 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. Mg(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 4-5°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), and two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), and two equivalent Mo(1) atoms.
SrMgMoO3 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. The Sr(1)-O(2) bond length is 2.48 Å. Both Sr(1)-O(1) bond lengths are 2.47 Å. Mg(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. The Mg(1)-O(2) bond length is 1.98 Å. Both Mg(1)-O(1) bond lengths are 1.99 Å. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 4-5°. There is one shorter (2.21 Å) and one longer (2.31 Å) Mo(1)-O(2) bond length. There are two shorter (2.21 Å) and two longer (2.30 Å) Mo(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), and two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Sr(1), one Mg(1), and two equivalent Mo(1) atoms.
