Materials Data on Ce5O9 by Materials Project
Ce5O9 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. there are two inequivalent Ce+3.60+ sites. In the first Ce+3.60+ site, Ce+3.60+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ce–O bond distances ranging from 2.29–2.43 Å. In the second Ce+3.60+ site, Ce+3.60+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.31 Å) and four longer (2.59 Å) Ce–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Ce+3.60+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra. In the second O2- site, O2- is bonded to four Ce+3.60+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra. In the third O2- site, O2- is bonded to four Ce+3.60+ atoms to form a mixture of distorted edge and corner-sharing OCe4 tetrahedra.
