The structure described by SmLaI4 crystallizes in the monoclinic C2/c space group. Sm(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. La(1) is bonded in a 8-coordinate geometry to four equivalent I(1) and four equivalent I(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and two equivalent La(1) atoms. In the second I site, I(2) is bonded to two equivalent Sm(1) and two equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing ILa2Sm2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
