The material structure described by MgTb2W2(O4Cl)2 crystallizes in the monoclinic C2 space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent Cl(1) atoms. Tb(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), and two equivalent Cl(1) atoms. W(1) is bonded in a distorted 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 T-shaped geometry to one Mg(1), one Tb(1), and one W(1) atom. In the second O site, O(2) is bonded in a T-shaped geometry to one Mg(1), one Tb(1), and one W(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Tb(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent Tb(1) and one W(1) atom. Cl(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1) and two equivalent Tb(1) atoms. is represented by the CIF file [CIF]
