description: (VOF3)4V2OF7 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one VOF3 ribbon oriented in the (1, 1, 0) direction; one V2OF7 sheet oriented in the (0, 0, 1) direction; and one VOF3 sheet oriented in the (0, 0, 1) direction. In the VOF3 ribbon, V+4.83+ is bonded in a 5-coordinate geometry to one O2- and four F1- atoms. The V–O bond length is 1.61 Å. There are a spread of V–F bond distances ranging from 1.77–1.97 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one V+4.83+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one V+4.83+ atom. The O–V bond length is 1.61 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the third F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V+4.83+ atoms. In the fourth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. The F–V bond length is 1.78 Å. In the fifth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. The F–V bond length is 1.77 Å. In the sixth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent V+4.83+ atoms. In the V2OF7 sheet, there are two inequivalent V+4.83+ sites. In the first V+4.83+ site, V+4.83+ is bonded in a 5-coordinate geometry to one O2- and four F1- atoms. The V–O bond length is 1.64 Å. There are a spread of V–F bond distances ranging from 1.76–1.94 Å. In the second V+4.83+ site, V+4.83+ is bonded in an octahedral geometry to one O2- and five F1- atoms. The V–O bond length is 2.18 Å. There are a spread of V–F bond distances ranging from 1.77–1.99 Å. O2- is bonded in a distorted bent 150 degrees geometry to two V+4.83+ atoms. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one V+4.83+ atom. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two V+4.83+ atoms. In the third F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the fifth F1- site, F1- is bonded in a bent 150 degrees geometry to two V+4.83+ atoms. In the sixth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the VOF3 sheet, there are two inequivalent V+4.83+ sites. In the first V+4.83+ site, V+4.83+ is bonded in a 6-coordinate geometry to two O2- and four F1- atoms. There is one shorter (1.66 Å) and one longer (2.13 Å) V–O bond length. There are a spread of V–F bond distances ranging from 1.77–2.27 Å. In the second V+4.83+ site, V+4.83+ is bonded in a 5-coordinate geometry to two O2- and three F1- atoms. There is one shorter (1.65 Å) and one longer (2.02 Å) V–O bond length. There are a spread of V–F bond distances ranging from 1.77–1.83 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two V+4.83+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two V+4.83+ atoms. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one V+4.83+ atom. In the sixth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two V+4.83+ atoms.
