The crystal structure described by MgLa2MoO6 is Ilmenite-derived structured and crystallizes in the triclinic P1 space group. Mg(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 MgO6 octahedra that share corners with three equivalent Mo(1)O6 octahedra, corners with six equivalent La(2)O6 octahedra, and  a faceface with one Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-58°. There are two inequivalent La sites. In the first La site, La(1) 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. In the second La site, La(2) 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 LaO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra and edges with three equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-58°. 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 corners with three equivalent Mg(1)O6 octahedra, edges with three equivalent La(2)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-43°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of distorted edge and corner-sharing OLa2MgMo trigonal pyramids. In the second O site, O(2) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of distorted edge and corner-sharing OLa2MgMo trigonal pyramids. In the third O site, O(3) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of edge and corner-sharing OLa2MgMo trigonal pyramids. In the fourth O site, O(4) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of distorted edge and corner-sharing OLa2MgMo trigonal pyramids. In the fifth O site, O(5) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of distorted edge and corner-sharing OLa2MgMo trigonal pyramids. In the sixth O site, O(6) is bonded to one Mg(1), one La(1), one La(2), and one Mo(1) atom to form a mixture of distorted edge and corner-sharing OLa2MgMo trigonal pyramids. is represented by the CIF file [CIF]
