Materials Data on FeN2Cl5O by Materials Project

FeN2OCl5 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four FeN2OCl5 clusters. Fe3+ is bonded in a 5-coordinate geometry to one O2- and four Cl1- atoms. The Fe–O bond length is 1.85 Å. There are a spread of Fe–Cl bond distances ranging from 2.23–2.39 Å. N2+ is bonded in a single-bond geometry to one Cl1- atom. The N–Cl bond length is 1.48 Å. O2- is bonded in a distorted single-bond geometry to one Fe3+ and three Cl1- atoms. There are two shorter (2.31 Å) and one longer (2.56 Å) O–Cl bond lengths. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two equivalent N2+ and one O2- atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Fe3+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Fe3+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Fe3+ and one O2- atom.
