Materials Data on Ba4In2O7 by Materials Project
Ba4In2O7 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Ba4In2O7 sheet oriented in the (0, 0, 1) direction. there are four inequivalent Ba2+ sites. In the first 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 2.68–3.06 Å. In the second Ba2+ site, Ba2+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.52–3.06 Å. In the third 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 2.66–3.07 Å. In the fourth Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.64–3.12 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to five O2- atoms to form distorted corner-sharing InO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 17°. There are one shorter (2.09 Å) and four longer (2.13 Å) In–O bond lengths. In the second In3+ site, In3+ is bonded to six O2- atoms to form corner-sharing InO6 octahedra. There are four shorter (2.21 Å) and two longer (2.24 Å) In–O bond lengths. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two In3+ atoms. In the second O2- site, O2- is bonded to five Ba2+ and one In3+ atom to form a mixture of distorted corner and edge-sharing OBa5In octahedra. The corner-sharing octahedra tilt angles range from 13–18°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two In3+ atoms. In the fourth O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two In3+ atoms. In the fifth O2- site, O2- is bonded to five Ba2+ and one In3+ atom to form a mixture of corner and edge-sharing OBa5In octahedra. The corner-sharing octahedra tilt angles range from 3–8°. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to four Ba2+ and one In3+ atom. In the seventh O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two In3+ atoms.
