The crystal structure described by MgY2Mo2(O4Cl)2 crystallizes in the monoclinic C2 space group. Mg(1) is bonded in a distorted octahedral geometry to two equivalent O(1), two equivalent O(3), and two equivalent Cl(1) atoms. Y(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), two equivalent O(1), two equivalent O(2), and one Cl(1) atom. Mo(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), two equivalent Y(1), and one Mo(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Y(1) and one Mo(1) atom. In the third O site, O(3) is bonded in a T-shaped geometry to one Mg(1), one Y(1), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a linear geometry to one Y(1) and one Mo(1) atom. Cl(1) is bonded in a distorted single-bond geometry to one Mg(1) and one Y(1) atom. is represented by the CIF card [CIF]
