The compound described by Ba2MgLaSbO6 crystallizes in the triclinic P1 space group. There are two inequivalent Ba sites. In the first Ba site, Ba(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 distorted BaO6 octahedra that share corners with three equivalent La(1)O6 octahedra and  a faceface with one La(1)O6 octahedra. The corner-sharing octahedral tilt angles are 63°. In the second Ba site, Ba(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 in a trigonal planar geometry to one O(2), one O(4), and one O(6) atom. La(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 LaO6 octahedra that share corners with three equivalent Ba(1)O6 octahedra and  a faceface with one Ba(1)O6 octahedra. The corner-sharing octahedral tilt angles are 63°. Sb(1) is bonded in a 3-coordinate geometry to one O(1), one O(3), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one La(1), and one Sb(1) atom. In the second O site, O(2) is bonded to one Ba(1), one Ba(2), one Mg(1), and one La(1) atom to form a mixture of distorted corner and edge-sharing OBa2LaMg tetrahedra. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one La(1), and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one Mg(1), and one La(1) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one La(1), and one Sb(1) atom. In the sixth O site, O(6) is bonded to one Ba(1), one Ba(2), one Mg(1), and one La(1) atom to form a mixture of distorted corner and edge-sharing OBa2LaMg tetrahedra. is represented by the CIF card [CIF]
