Abstract

CeSiO2N crystallizes in the hexagonal P-6c2 space group. The structure is three-dimensional. there are three inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to six equivalent N3- and six equivalent O2- atoms to form CeN6O6 cuboctahedra that share edges with six CeO6 octahedra, faces with two equivalent CeN6O6 cuboctahedra, and faces with six equivalent SiN2O2 tetrahedra. All Ce–N bond lengths are 2.92 Å. All Ce–O bond lengths are 2.79 Å. In the second Ce3+ site, Ce3+ is bonded to six equivalent O2- atoms to form distorted CeO6 octahedra that share corners with six equivalent SiN2O2 tetrahedra, edges with three equivalent CeN6O6 cuboctahedra, and edges with three equivalent CeO6 octahedra. All Ce–O bond lengths are 2.44 Å. In the third Ce3+ site, Ce3+ is bonded to six equivalent O2- atoms to form distorted CeO6 octahedra that share corners with six equivalent SiN2O2 tetrahedra, edges with three equivalent CeN6O6 cuboctahedra, and edges with three equivalent CeO6 octahedra. All Ce–O bond lengths are 2.47 Å. Si4+ is bonded to two equivalent N3- and two equivalent O2- atoms to form SiN2O2 tetrahedra that share corners with four CeO6 octahedra, corners with two equivalent SiN2O2 tetrahedra, and faces with two equivalent CeN6O6more »« less
