Abstract

MgO10(Fe2S3O16)2(O2)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two oxygen molecules; one MgO10 cluster; and two Fe2S3O16 ribbons oriented in the (1, 1, 0) direction. In the MgO10 cluster, Mg is bonded in a distorted octahedral geometry to six O atoms. There are a spread of Mg–O bond distances ranging from 2.04–2.58 Å. There are five inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Mg atom. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom. The O–O bond length is 1.32 Å. In the third O site, O is bonded in a single-bond geometry to one Mg atom. In the fourth O site, O is bonded in a bent 120 degrees geometry to two O atoms. The O–O bond length is 1.26 Å. In the fifth O site, O is bonded in a single-bond geometry to one O atom. In each Fe2S3O16 ribbon, there are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Fe–O bond distances ranging from 1.89–2.07 Å. In the second Fe site, Fe is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Fe–O bond distances ranging from 1.88–2.07 Å. There are three inequivalent S sites. In the first S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.45–1.54 Å. 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 1.45–1.54 Å. In the third S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.45–1.55 Å. There are sixteen inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Fe and one S atom. In the second O site, O is bonded in a single-bond geometry to one S atom. In the third O site, O is bonded in a bent 120 degrees geometry to one Fe and one S atom. In the fourth O site, O is bonded in a single-bond geometry to one S atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Fe and 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 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 single-bond geometry to one S atom. In the tenth O site, O is bonded in a bent 120 degrees geometry to one Fe and 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 the thirteenth O site, O is bonded in a 2-coordinate geometry to one Fe and one O atom. The O–O bond length is 1.31 Å. In the fourteenth O site, O is bonded in a 2-coordinate geometry to one Fe and one O atom. In the fifteenth 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 sixteenth O site, O is bonded in a 2-coordinate geometry to one Fe and one O atom.
