Materials Data on CeBi2SeO4 by Materials Project
CeBi2SeO4 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ce4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ce–O bond lengths are 2.38 Å. Bi3+ is bonded in a 4-coordinate geometry to four equivalent Se2- and four equivalent O2- atoms. All Bi–Se bond lengths are 3.32 Å. All Bi–O bond lengths are 2.33 Å. Se2- is bonded in a distorted body-centered cubic geometry to eight equivalent Bi3+ atoms. O2- is bonded to two equivalent Ce4+ and two equivalent Bi3+ atoms to form a mixture of edge and corner-sharing OCe2Bi2 tetrahedra.
