The structure described by SmV2O9I crystallizes in the orthorhombic Pbcm space group. Sm(1) is bonded in a 9-coordinate geometry to one O(2), one O(6), one O(7), two equivalent O(3), and four equivalent O(1) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(5), two equivalent O(3), and two equivalent O(4) atoms to form distorted corner-sharing VO5 trigonal bipyramids. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(4), one O(6), one O(7), and two equivalent O(5) atoms. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one V(2) and two equivalent V(1) atoms. In the second O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one V(1) and two equivalent V(2) atoms. In the third O site, O(6) is bonded in a distorted linear geometry to one Sm(1) and one V(2) atom. In the fourth O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one I(1) atom. In the fifth O site, O(7) is bonded in a distorted single-bond geometry to one Sm(1) and one V(2) atom. In the sixth O site, O(2) is bonded in a linear geometry to one Sm(1) and one I(1) atom. In the seventh O site, O(3) is bonded in a distorted single-bond geometry to one Sm(1) and one V(1) atom. I(1) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) atoms. is represented by the CIF card [CIF]
