Materials Data on BaBiBO4 by Materials Project
BaBiBO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.08 Å. B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.38–1.40 Å. Bi3+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Bi–O bond distances ranging from 2.04–2.63 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one B3+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one B3+, and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+, one B3+, and one Bi3+ atom. In the fourth O2- site, O2- is bonded to three equivalent Ba2+ and one Bi3+ atom to form a mixture of distorted corner and edge-sharing OBa3Bi tetrahedra.
