The material structure described by SmO2Cl crystallizes in the monoclinic P2_1/m space group. Sm(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent Cl(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sm(1) and two equivalent O(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent Sm(1) atoms. Cl(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sm(1) atoms. is represented by the CIF file [CIF]
