SmI2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. Sm(1) is bonded to three equivalent I(1) and four equivalent I(2) atoms to form a mixture of distorted corner and edge-sharing SmI7 pentagonal bipyramids. There are two inequivalent I sites. In the first I site, I(1) is bonded in a trigonal planar geometry to three equivalent Sm(1) atoms. In the second I site, I(2) is bonded to four equivalent Sm(1) atoms to form a mixture of distorted corner and edge-sharing ISm4 trigonal pyramids.
