SmOCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Sm(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 Sm(1) atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to five equivalent Sm(1) atoms.
SmOCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Sm(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. All Sm(1)-O(1) bond lengths are 2.31 Å. There is one shorter (3.07 Å) and four longer (3.13 Å) Sm(1)-Cl(1) bond lengths. O(1) is bonded to four equivalent Sm(1) atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to five equivalent Sm(1) atoms.
