Materials Data on ZrI4 by Materials Project
ZrI4 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one ZrI4 cluster. there are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to six I1- atoms to form ZrI6 octahedra that share an edgeedge with one ZrI6 octahedra and an edgeedge with one ZrI5 trigonal bipyramid. There are a spread of Zr–I bond distances ranging from 2.73–3.08 Å. In the second Zr4+ site, Zr4+ is bonded to five I1- atoms to form edge-sharing ZrI5 trigonal bipyramids. There are a spread of Zr–I bond distances ranging from 2.71–3.07 Å. There are eight inequivalent I1- sites. In the first I1- site, I1- is bonded in a water-like geometry to two equivalent Zr4+ atoms. In the second I1- site, I1- is bonded in a water-like geometry to two Zr4+ atoms. In the third I1- site, I1- is bonded in a water-like geometry to two Zr4+ atoms. In the fourth I1- site, I1- is bonded in a single-bond geometry to one Zr4+ atom. In the fifth I1- site, I1- is bonded in a single-bond geometry to one Zr4+ atom. In the sixth I1- site, I1- is bonded in a single-bond geometry to one Zr4+ atom. In the seventh I1- site, I1- is bonded in a single-bond geometry to one Zr4+ atom. In the eighth I1- site, I1- is bonded in a single-bond geometry to one Zr4+ atom.
