Cs2MgV2Mn(O3Br)2 crystallizes in the orthorhombic Cmm2 space group. Cs(1) is bonded in a 9-coordinate geometry to one Mg(1), two equivalent O(1), two equivalent O(2), three equivalent O(3), and one Br(1) atom. Mg(1) is bonded in a 3-coordinate geometry to two equivalent Cs(1), one Br(1), and two equivalent Br(2) atoms. V(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form corner-sharing VO4 tetrahedra. Mn(1) is bonded in a 2-coordinate geometry to two equivalent O(2), one Br(2), and two equivalent Br(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Cs(1) and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Cs(1), one V(1), and one Mn(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one V(1) atom. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded to two equivalent Cs(1), one Mg(1), and two equivalent Mn(1) atoms to form distorted corner-sharing BrCs2MgMn2 trigonal bipyramids. In the second Br site, Br(2) is bonded in a 3-coordinate geometry to two equivalent Mg(1) and one Mn(1) atom.
