DyOCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. O(1) is bonded to four equivalent Dy(1) atoms to form a mixture of corner and edge-sharing ODy4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to five equivalent Dy(1) atoms.
DyOCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. All Dy(1)-O(1) bond lengths are 2.25 Å. There are four shorter (3.09 Å) and one longer (3.10 Å) Dy(1)-Cl(1) bond length. O(1) is bonded to four equivalent Dy(1) atoms to form a mixture of corner and edge-sharing ODy4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to five equivalent Dy(1) atoms.
