Materials Data on Ba2V3O9 by Materials Project
Ba2V3O9 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Ba–O bond distances ranging from 2.70–3.11 Å. In the second Ba2+ site, Ba2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ba–O bond distances ranging from 2.71–2.89 Å. There are three inequivalent V+4.67+ sites. In the first V+4.67+ site, V+4.67+ is bonded to six O2- atoms to form VO6 octahedra that share corners with four VO4 tetrahedra and edges with two equivalent VO6 octahedra. There are a spread of V–O bond distances ranging from 1.75–2.05 Å. In the second V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form corner-sharing VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 44–50°. There are a spread of V–O bond distances ranging from 1.69–1.86 Å. In the third V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form corner-sharing VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–60°. There are a spread of V–O bond distances ranging from 1.70–1.79 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+ and two V+4.67+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V+4.67+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ba2+ and one V+4.67+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one V+4.67+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V+4.67+ atom. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to three V+4.67+ atoms. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+ and two V+4.67+ atoms. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+ and one V+4.67+ atom. In the ninth O2- site, O2- is bonded in a distorted water-like geometry to one Ba2+ and two equivalent V+4.67+ atoms.
