There are a spread of Bi–O bond distances ranging from 2.12–2.40 Å. In the twenty-eighth Bi+2.83+ site, Bi+2.83+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.13–2.53 Å. In the twenty-ninth Bi+2.83+ site, Bi+2.83+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Bi–O bond distances ranging from 2.12–2.46 Å. In the thirtieth Bi+2.83+ site, Bi+2.83+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.13–2.23 Å. In the thirty-first Bi+2.83+ site, Bi+2.83+ is bonded to five O2- atoms to form distorted BiO5 square pyramids that share corners with two CaO5 trigonal bipyramids, a cornercorner with one BiO4 trigonal pyramid, an edgeedge with one CaO6 pentagonal pyramid, and an edgeedge with one CaO4 trigonal pyramid.
