title: Materials Data on CeSe2 by Materials Project

description: CeSe2 is Low Tridymite structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are twelve inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.72 Å) and one longer (2.73 Å) Ce–Se bond lengths. In the second Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are a spread of Ce–Se bond distances ranging from 2.72–2.74 Å. In the third Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are two shorter (2.71 Å) and two longer (2.72 Å) Ce–Se bond lengths. In the fourth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. All Ce–Se bond lengths are 2.72 Å. In the fifth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are two shorter (2.71 Å) and two longer (2.72 Å) Ce–Se bond lengths. In the sixth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.72 Å) and one longer (2.73 Å) Ce–Se bond lengths. In the seventh Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.71 Å) and one longer (2.72 Å) Ce–Se bond lengths. In the eighth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.73 Å) and one longer (2.74 Å) Ce–Se bond lengths. In the ninth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are a spread of Ce–Se bond distances ranging from 2.71–2.73 Å. In the tenth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. All Ce–Se bond lengths are 2.72 Å. In the eleventh Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. All Ce–Se bond lengths are 2.73 Å. In the twelfth Ce4+ site, Ce4+ is bonded to four Se2- atoms to form corner-sharing CeSe4 tetrahedra. There are three shorter (2.72 Å) and one longer (2.73 Å) Ce–Se bond lengths.
