Dy(O2Cl)3 crystallizes in the monoclinic P2/c space group. Dy(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent Cl(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Dy(1) and one Cl(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Dy(1) and one O(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Dy(1) and one Cl(2) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted water-like geometry to one Dy(1) and one O(1) atom. In the second Cl site, Cl(2) is bonded in a bent 120 degrees geometry to two equivalent O(3) atoms.
