Ba2MgLuBiO6 crystallizes in the triclinic P-1 space group. Ba(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. Lu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LuO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-31°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted BiO6 octahedra that share corners with six equivalent Lu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-31°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Mg(1), one Lu(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1), one Lu(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Mg(1), one Lu(1), and one Bi(1) atom.
