The material described by Ba2MgLaBiO6 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a distorted pentagonal planar geometry to one O(2) and four equivalent O(1) atoms. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share faces with two equivalent Bi(1)O6 octahedra. La(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Bi(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted BiO6 octahedra that share faces with two equivalent Mg(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ba(1), one Mg(1), one La(1), and one Bi(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa2LaMgBi trigonal bipyramids. In the second O site, O(2) is bonded in a T-shaped geometry to one Ba(1), one Mg(1), and one Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
