The material described by SmO2Cl crystallizes in the monoclinic P2_1/m space group. Sm(1) is bonded in a 10-coordinate geometry to three equivalent O(2), four equivalent O(1), and three equivalent Cl(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and one O(2) atom. In the second O site, O(2) is bonded to three equivalent Sm(1) and one O(1) atom to form a mixture of corner and edge-sharing OSm3O trigonal pyramids. Cl(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
