CeSe2 is High (Orthorhombic) Tridymite-like structured and crystallizes in the orthorhombic Fddd space group. Ce(1) is bonded to two equivalent Se(1) and two equivalent Se(2) atoms to form corner-sharing CeSe4 tetrahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a bent 150 degrees geometry to two equivalent Ce(1) atoms. In the second Se site, Se(2) is bonded in a linear geometry to two equivalent Ce(1) atoms.
CeSe2 is High (Orthorhombic) Tridymite-like structured and crystallizes in the orthorhombic Fddd space group. Ce(1) is bonded to two equivalent Se(1) and two equivalent Se(2) atoms to form corner-sharing CeSe4 tetrahedra. Both Ce(1)-Se(1) bond lengths are 2.72 Å. Both Ce(1)-Se(2) bond lengths are 2.71 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a bent 150 degrees geometry to two equivalent Ce(1) atoms. In the second Se site, Se(2) is bonded in a linear geometry to two equivalent Ce(1) atoms.
