MgLa2MoO6 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), and four equivalent O(4) atoms. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to two equivalent O(1) and four equivalent O(4) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to one O(2), one O(3), and four equivalent O(4) atoms. Mo(1) is bonded in a distorted tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one La(1) and one Mo(1) atom. In the second O site, O(2) is bonded in a T-shaped geometry to one Mg(1), one La(2), and one Mo(1) atom. In the third O site, O(3) is bonded in a T-shaped geometry to one Mg(1), one La(2), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent La(1), and two equivalent La(2) atoms.
