Materials Data on FeH2Cl5O3 by Materials Project

Abstract

FeH2O3Cl5 is High Pressure (4-7GPa) Tellurium structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four FeH2O3Cl5 clusters. Fe is bonded in a 6-coordinate geometry to one O and five Cl atoms. The Fe–O bond length is 1.92 Å. There are a spread of Fe–Cl bond distances ranging from 2.29–2.58 Å. H is bonded in a single-bond geometry to one O atom. The H–O bond length is 1.00 Å. There are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Fe atom. In the second O site, O is bonded in a single-bond geometry to one H and one Cl atom. The O–Cl bond length is 2.30 Å. There are four inequivalent Cl sites. In the first Cl site, Cl is bonded in a single-bond geometry to one Fe atom. In the second Cl site, Cl is bonded in a distorted trigonal non-coplanar geometry to one Fe and two equivalent O atoms. In the third Cl site, Cl is bonded in a single-bond geometry to one Fe atom. In the fourth Cl site, Cl is bonded in a single-bond geometry to one Fe atom.
