Materials Data on Ce2SeO2 by Materials Project
Abstract
Ce2SeO2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Ce3+ is bonded in a 4-coordinate geometry to three equivalent Se2- and four equivalent O2- atoms. All Ce–Se bond lengths are 3.08 Å. There are one shorter (2.37 Å) and three longer (2.38 Å) Ce–O bond lengths. Se2- is bonded to six equivalent Ce3+ atoms to form distorted SeCe6 octahedra that share corners with twelve equivalent OCe4 tetrahedra, edges with six equivalent SeCe6 octahedra, and edges with six equivalent OCe4 tetrahedra. O2- is bonded to four equivalent Ce3+ atoms to form OCe4 tetrahedra that share corners with six equivalent SeCe6 octahedra, corners with six equivalent OCe4 tetrahedra, edges with three equivalent SeCe6 octahedra, and edges with three equivalent OCe4 tetrahedra. The corner-sharing octahedra tilt angles range from 27–48°.
