Cs2Mg(MoO6)2 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 10-coordinate geometry to one O(5), one O(6), two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Mg(1) is bonded in an octahedral geometry to two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms. Mo(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites.
