The structure 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 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 Ba site, Ba(2) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(6) atom. Mg(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), one O(4), and one O(6) atom. La(1) is bonded in a distorted octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Sb(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like 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 edge and corner-sharing OBa2LaMg tetrahedra. In the third O site, O(3) is bonded to one Ba(1), one Ba(2), one Mg(1), and one La(1) atom to form a mixture of distorted edge and corner-sharing OBa2LaMg tetrahedra. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ba(2), one Mg(1), one La(1), and one Sb(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Ba(1), one La(1), and one Sb(1) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one Mg(1), and one La(1) atom. is represented by the CIF file [CIF]
