Materials Data on CeSnO4 by Materials Project
CeSnO4 is alpha bismuth trifluoride-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are six shorter (2.33 Å) and two longer (2.44 Å) Ce–O bond lengths. Sn4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.26 Å) and six longer (2.27 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Ce4+ and one Sn4+ atom to form a mixture of corner and edge-sharing OCe3Sn tetrahedra. In the second O2- site, O2- is bonded to one Ce4+ and three equivalent Sn4+ atoms to form a mixture of corner and edge-sharing OCeSn3 tetrahedra.
