The structure described by Ba2MgMoMnO6 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Ba(1), two equivalent O(1), and two equivalent O(3) atoms. Mo(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(3) 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 Mo(1), and one Mn(1) atom to form a mixture of distorted corner, edge, and face-sharing OBa2MgMnMo trigonal bipyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one Mo(1) atom. In the third O site, O(3) is bonded to two equivalent Ba(1), one Mg(1), one Mo(1), and one Mn(1) atom to form a mixture of distorted corner, edge, and face-sharing OBa2MgMnMo trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
