The structure described by Ba2SrMgWO6 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. Sr(1) is bonded in a square co-planar geometry to 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 W(1)O6 octahedra. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 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 Sr(1), one Mg(1), and one W(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa2SrMgW 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 W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
