Ba2MgWMnO6 crystallizes in the triclinic P-1 space group. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Ba(1), two equivalent O(1), and two equivalent O(2) atoms. W(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Mn(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ba(1), one Mg(1), one W(1), and one Mn(1) atom to form a mixture of distorted face, corner, and edge-sharing OBa2MgMnW trigonal bipyramids. In the second O site, O(2) is bonded to two equivalent Ba(1), one Mg(1), one W(1), and one Mn(1) atom to form a mixture of distorted face, corner, and edge-sharing OBa2MgMnW trigonal bipyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one W(1) atom.
