The material described by GdWO4Cl crystallizes in the monoclinic C2/m space group. Gd(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), four equivalent O(2), and two equivalent Cl(1) atoms. W(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Gd(1) and one W(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Gd(1) and one W(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Gd(1) and one W(1) atom. Cl(1) is bonded in a water-like geometry to two equivalent Gd(1) atoms. is represented by the CIF file [CIF]
