The compound described by Na2Mg(MoO3)2 crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(5), and one O(6) atom to form distorted MgO5 trigonal bipyramids that share  a cornercorner with one Mo(1)O6 octahedra, edges with two equivalent Mo(1)O6 octahedra, and edges with two equivalent Mo(2)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 11°. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MoO6 octahedra that share  a cornercorner with one Mg(1)O5 trigonal bipyramid, corners with five equivalent Mo(2)O5 trigonal bipyramids, and edges with two equivalent Mg(1)O5 trigonal bipyramids. In the second Mo site, Mo(2) is bonded to one O(1), one O(3), one O(4), one O(5), and one O(6) atom to form distorted MoO5 trigonal bipyramids that share corners with five equivalent Mo(1)O6 octahedra and edges with two equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 2-54°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), one Na(2), one Mg(1), one Mo(1), and one Mo(2) atom to form a mixture of distorted corner and edge-sharing ONa2MgMo2 trigonal bipyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Na(1), one Na(2), one Mg(1), and one Mo(1) atom. In the third O site, O(3) is bonded to one Na(1), one Na(2), one Mg(1), one Mo(1), and one Mo(2) atom to form a mixture of corner and edge-sharing ONa2MgMo2 square pyramids. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(2), one Mo(1), and one Mo(2) atom. In the fifth O site, O(5) is bonded to one Na(1), one Na(2), one Mg(1), one Mo(1), and one Mo(2) atom to form a mixture of corner and edge-sharing ONa2MgMo2 square pyramids. In the sixth O site, O(6) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Mg(1), one Mo(1), and one Mo(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
