Materials Data on FeH8(ClO2)2 by Materials Project
FeCl2(H2O)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two 13478-10-9 molecules. Fe2+ is bonded in an octahedral geometry to four O2- and two equivalent Cl1- atoms. There are two shorter (2.11 Å) and two longer (2.13 Å) Fe–O bond lengths. Both Fe–Cl bond lengths are 2.55 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. Cl1- is bonded in a single-bond geometry to one Fe2+ atom.
