The material structure described by In3SnI5 crystallizes in the monoclinic C2/c space group. There are four inequivalent In sites. In the first In site, In(1) is bonded in a distorted L-shaped geometry to two equivalent I(1) and two equivalent I(2) atoms. In the second In site, In(2) is bonded in a 4-coordinate geometry to one I(3), one I(4), and two equivalent I(2) atoms. In the third In site, In(3) is bonded in a 4-coordinate geometry to two equivalent I(2) and two equivalent I(5) atoms. In the fourth In site, In(4) is bonded in a 5-coordinate geometry to one I(1), one I(3), one I(4), and two equivalent I(5) atoms. Sn(1) is bonded to one I(1), one I(2), one I(3), one I(5), and two equivalent I(4) atoms to form edge-sharing SnI6 octahedra. There are five inequivalent I sites. In the first I site, I(1) is bonded in a 3-coordinate geometry to one In(1), one In(4), and one Sn(1) atom. In the second I site, I(2) is bonded in a 5-coordinate geometry to one In(1), one In(3), two equivalent In(2), and one Sn(1) atom. In the third I site, I(3) is bonded in a distorted L-shaped geometry to one In(2), one In(4), and one Sn(1) atom. In the fourth I site, I(4) is bonded in a 4-coordinate geometry to one In(2), one In(4), and two equivalent Sn(1) atoms. In the fifth I site, I(5) is bonded in a distorted see-saw-like geometry to one In(3), two equivalent In(4), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
