TaI5 is Indium-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four TaI5 clusters. Ta(1) is bonded to one I(1), one I(2), one I(3), one I(4), one I(5), and one I(6) atom to form edge-sharing TaI6 octahedra. There are six inequivalent I sites. In the first I site, I(1) is bonded in a single-bond geometry to one Ta(1) atom. In the second I site, I(2) is bonded in a water-like geometry to two equivalent Ta(1) atoms. In the third I site, I(3) is bonded in a single-bond geometry to one Ta(1) atom. In the fourth I site, I(4) is bonded in a water-like geometry to two equivalent Ta(1) atoms. In the fifth I site, I(5) is bonded in a single-bond geometry to one Ta(1) atom. In the sixth I site, I(6) is bonded in a single-bond geometry to one Ta(1) atom.
