Materials Data on Fe2S3O23 by Materials Project
FeSO7Fe(SO6)2(O2)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four molecular oxygen molecules, two Fe(SO6)2 clusters, and two FeSO7 clusters. In each Fe(SO6)2 cluster, Fe is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Fe–O bond distances ranging from 1.86–2.41 Å. There are two inequivalent S sites. In the first S site, S is bonded in a tetrahedral geometry to four O atoms. There is three shorter (1.47 Å) and one longer (1.54 Å) S–O bond length. In the second S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.46–1.54 Å. There are twelve inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one S atom. In the second O site, O is bonded in a 2-coordinate geometry to one Fe and one O atom. The O–O bond length is 1.30 Å. 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 single-bond geometry to one O atom. The O–O bond length is 1.24 Å. 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 120 degrees geometry to one Fe and one S atom. In the seventh O site, O is bonded in a water-like geometry to one Fe and one O atom. In the eighth O site, O is bonded in a 2-coordinate geometry to one Fe and one O atom. In the ninth O site, O is bonded in a single-bond geometry to one S atom. In the tenth O site, O is bonded in a single-bond geometry to one S atom. In the eleventh O site, O is bonded in a single-bond geometry to one S atom. In the twelfth O site, O is bonded in a bent 150 degrees geometry to one Fe and one S atom. In each FeSO7 cluster, Fe is bonded in a see-saw-like geometry to four O atoms. There are a spread of Fe–O bond distances ranging from 1.66–1.84 Å. S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.46–1.56 Å. There are seven inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Fe and one S atom. In the second O site, O is bonded in a single-bond geometry to one Fe atom. In the third O site, O is bonded in a single-bond geometry to one Fe atom. In the fourth O site, O is bonded in a single-bond geometry to one Fe 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 single-bond geometry to one S atom. In the seventh O site, O is bonded in a single-bond geometry to one S atom.
