NbI5 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one NbI5 cluster. Nb(1) is bonded to one I(1), one I(3), one I(4), one I(5), and two equivalent I(2) atoms to form edge-sharing NbI6 octahedra. There are five inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Nb(1) atom. In the second I site, I(2) is bonded in a water-like geometry to two equivalent Nb(1) atoms. In the third I site, I(3) is bonded in a single-bond geometry to one Nb(1) atom. In the fourth I site, I(4) is bonded in a single-bond geometry to one Nb(1) atom. In the fifth I site, I(5) is bonded in a single-bond geometry to one Nb(1) atom.
