The material described by Dy(O4Cl)3 crystallizes in the trigonal R3c space group. Dy(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Dy(1) and 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 single-bond geometry to one Cl(1) atom. In the fourth O site, O(4) is bonded in a water-like 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), one O(3), and one O(4) atom. is represented by the CIF file [CIF]
