The compound described by Ba2MgBiSbO6 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 5-coordinate 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 Sb(1)O6 octahedra. Bi(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 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 Bi(1), and one Sb(1) atom to form a mixture of distorted corner, edge, and face-sharing OBa2MgBiSb trigonal bipyramids. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Ba(1), one Mg(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
