Materials Data on Sr5(BiO4)3 by Materials Project
Sr5(BiO4)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Sr sites. In the first Sr site, Sr is bonded to six O atoms to form SrO6 octahedra that share corners with six BiO6 octahedra. The corner-sharing octahedra tilt angles range from 32–38°. There are a spread of Sr–O bond distances ranging from 2.40–2.45 Å. In the second Sr site, Sr is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Sr–O bond distances ranging from 2.49–2.97 Å. In the third Sr site, Sr is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Sr–O bond distances ranging from 2.50–3.17 Å. There are three inequivalent Bi sites. In the first Bi site, Bi is bonded to six O atoms to form BiO6 octahedra that share corners with two equivalent SrO6 octahedra and corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 31–38°. There are a spread of Bi–O bond distances ranging from 2.09–2.24 Å. In the second Bi site, Bi is bonded to six O atoms to form corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 31–37°. There are four shorter (2.27 Å) and two longer (2.29 Å) Bi–O bond lengths. In the third Bi site, Bi is bonded to six O atoms to form BiO6 octahedra that share corners with two equivalent BiO6 octahedra and corners with four equivalent SrO6 octahedra. The corner-sharing octahedra tilt angles range from 32–37°. There are a spread of Bi–O bond distances ranging from 2.10–2.28 Å. There are six inequivalent O sites. In the first O site, O is bonded to three Sr and one Bi atom to form distorted corner-sharing OSr3Bi tetrahedra. In the second O site, O is bonded in a 4-coordinate geometry to two Sr and two Bi atoms. In the third O site, O is bonded in a 5-coordinate geometry to four Sr and one Bi atom. In the fourth O site, O is bonded in a 5-coordinate geometry to three Sr and two Bi atoms. In the fifth O site, O is bonded in a 5-coordinate geometry to four Sr and one Bi atom. In the sixth O site, O is bonded to two Sr and two Bi atoms to form distorted corner-sharing OSr2Bi2 tetrahedra.
