Sr2MgWZnO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent O(1), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(1) atoms. W(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. Zn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Mg(1), one W(1), and one Zn(1) atom to form distorted OSr2MgZnW trigonal bipyramids that share corners with three equivalent O(1)Sr2MgZnW trigonal bipyramids, corners with six equivalent O(2)Sr4W trigonal bipyramids, edges with two equivalent O(2)Sr4W trigonal bipyramids, edges with three equivalent O(1)Sr2MgZnW trigonal bipyramids, and faces with two equivalent O(1)Sr2MgZnW trigonal bipyramids. In the second O site, O(2) is bonded to four equivalent Sr(1) and one W(1) atom to form distorted OSr4W trigonal bipyramids that share corners with five equivalent O(2)Sr4W trigonal bipyramids, corners with twelve equivalent O(1)Sr2MgZnW trigonal bipyramids, edges with four equivalent O(1)Sr2MgZnW trigonal bipyramids, and edges with four equivalent O(2)Sr4W trigonal bipyramids.
