GaI3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two GaI3 clusters. Ga(1) is bonded to one I(1), one I(2), and two equivalent I(3) atoms to form edge-sharing GaI4 tetrahedra. There are three inequivalent I sites. In the first I site, I(2) is bonded in a single-bond geometry to one Ga(1) atom. In the second I site, I(1) is bonded in a single-bond geometry to one Ga(1) atom. In the third I site, I(3) is bonded in an L-shaped geometry to two equivalent Ga(1) atoms.

Ga(1) is bonded to one I(1), one I(2), and two equivalent I(3) atoms to form edge-sharing GaI4 tetrahedra. The Ga(1)-I(1) bond length is 2.49 Å. The Ga(1)-I(2) bond length is 2.50 Å. Both Ga(1)-I(3) bond lengths are 2.69 Å. There are three inequivalent I sites. In the first I site, I(2) is bonded in a single-bond geometry to one Ga(1) atom.
