Materials Data on Fe2S2O13 by Materials Project

(FeSO5)4(O2)3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of three oxygen molecules and one FeSO5 ribbon oriented in the (0, 1, 0) direction. In the FeSO5 ribbon, there are two inequivalent Fe sites. In the first Fe site, Fe is bonded to five O atoms to form distorted FeO5 trigonal bipyramids that share corners with two equivalent FeO4 tetrahedra, corners with three SO4 tetrahedra, and an edgeedge with one FeO5 trigonal bipyramid. There are a spread of Fe–O bond distances ranging from 1.94–2.01 Å. In the second Fe site, Fe is bonded to four O atoms to form FeO4 tetrahedra that share corners with two SO4 tetrahedra and corners with two equivalent FeO5 trigonal bipyramids. There are a spread of Fe–O bond distances ranging from 1.70–1.94 Å. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share a cornercorner with one FeO4 tetrahedra and a cornercorner with one FeO5 trigonal bipyramid. There are a spread of S–O bond distances ranging from 1.45–1.55 Å. In the second S site, S is bonded to four O atoms to form SO4 tetrahedra that share a cornercorner with one FeO4 tetrahedra and corners with two equivalent FeO5 trigonal bipyramids. There are a spread of S–O bond distances ranging from 1.45–1.52 Å. There are ten 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 bent 120 degrees geometry to one Fe and one S atom. In the third O site, O is bonded in a single-bond geometry to one S atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Fe and one S atom. In the fifth O site, O is bonded in a single-bond geometry to one S atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Fe and one S atom. In the seventh O site, O is bonded in a distorted bent 120 degrees geometry to one Fe and one S atom. In the eighth O site, O is bonded in a single-bond geometry to one S atom. In the ninth O site, O is bonded in a bent 150 degrees geometry to one Fe and one S atom. In the tenth O site, O is bonded in a trigonal planar geometry to three Fe atoms.

Materials Data on FeSO8 by Materials Project

(Fe2S2O13)2(O2)3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two oxygen molecules; two water molecules; and one Fe2S2O13 ribbon oriented in the (1, 0, 0) direction. In the Fe2S2O13 ribbon, there are two inequivalent Fe sites. In the first Fe site, Fe is bonded to five O atoms to form FeO5 trigonal bipyramids that share corners with three SO4 tetrahedra and an edgeedge with one FeO5 trigonal bipyramid. There are a spread of Fe–O bond distances ranging from 1.96–2.01 Å. In the second Fe site, Fe is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Fe–O bond distances ranging from 1.94–2.39 Å. There are two inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share a cornercorner with one FeO5 trigonal bipyramid. There are a spread of S–O bond distances ranging from 1.46–1.52 Å.
