Materials Data on Al(Bi3O5)4 by Materials Project
Al(Bi3O5)4 crystallizes in the cubic I23 space group. The structure is three-dimensional. Al3+ is bonded to four equivalent O2- atoms to form AlO4 tetrahedra that share corners with twelve equivalent BiO5 square pyramids. All Al–O bond lengths are 1.80 Å. Bi+3.08+ is bonded to five O2- atoms to form distorted BiO5 square pyramids that share corners with eight equivalent BiO5 square pyramids, a cornercorner with one AlO4 tetrahedra, and an edgeedge with one BiO5 square pyramid. There are a spread of Bi–O bond distances ranging from 2.11–2.61 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Bi+3.08+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Al3+ and three equivalent Bi+3.08+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three equivalent Bi+3.08+ atoms.
