InI3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two InI3 clusters. In(1) is bonded to one I(1), one I(3), and two equivalent I(2) atoms to form edge-sharing InI4 tetrahedra. There are three inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one In(1) atom. In the second I site, I(2) is bonded in an L-shaped geometry to two equivalent In(1) atoms. In the third I site, I(3) is bonded in a single-bond geometry to one In(1) atom.

In(1) is bonded to one I(1), one I(3), and two equivalent I(2) atoms to form edge-sharing InI4 tetrahedra. The In(1)-I(1) bond length is 2.67 Å. The In(1)-I(3) bond length is 2.67 Å. Both In(1)-I(2) bond lengths are 2.87 Å. There are three inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one In(1) atom.
