The structure described by Dy(O4Cl)3 crystallizes in the hexagonal P6_3/m space group. Dy(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Cl(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Dy(1) and one Cl(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Dy(1) and one Cl(1) atom. Cl(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
