SbI3 is Bismuth triodide structured and crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three SbI3 sheets oriented in the (0, 0, 1) direction. Sb3+ is bonded to six equivalent I1- atoms to form edge-sharing SbI6 octahedra. There are three shorter (3.03 Å) and three longer (3.09 Å) Sb–I bond lengths. I1- is bonded in an L-shaped geometry to two equivalent Sb3+ atoms.
SbI3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one SbI3 sheet oriented in the (1, 0, 0) direction. Sb3+ is bonded to five I1- atoms to form a mixture of distorted edge and corner-sharing SbI5 square pyramids. There are a spread of Sb–I bond distances ranging from 2.81–3.52 Å. There are three inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted water-like geometry to two equivalent Sb3+ atoms. In the second I1- site, I1- is bonded in a distorted water-like geometry to two equivalent Sb3+ atoms. In the third I1- site, I1- is bonded in a single-bond geometry to one Sb3+ atom.
