Title: Materials Data on CaCeAl2FeSi3O13 by Materials Project

Abstract

CaCeFeAl2Si3O13 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.36–2.55 Å. Ce3+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Ce–O bond distances ranging from 2.17–2.67 Å. Fe3+ is bonded to six O2- atoms to form distorted FeO6 octahedra that share corners with five SiO4 tetrahedra and edges with two equivalent AlO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.94–2.36 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four SiO4 tetrahedra, edges with two equivalent FeO6 octahedra, and edges with two equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.82–2.04 Å. In the second Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four SiO4 tetrahedra and edges with two equivalent AlO6 octahedra. There is four shorter (1.89 Å) and two longer (1.97 Å) Al–O bond length. There are three inequivalent Si4+ sites.more » In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent FeO6 octahedra, corners with two equivalent AlO6 octahedra, and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one FeO6 octahedra, corners with two equivalent AlO6 octahedra, and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–54°. There are a spread of Si–O bond distances ranging from 1.61–1.66 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent FeO6 octahedra and corners with four AlO6 octahedra. The corner-sharing octahedra tilt angles range from 48–58°. There is three shorter (1.65 Å) and one longer (1.66 Å) Si–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Al3+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+, one Ce3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Fe3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the fifth O2- site, O2- is bonded in a trigonal non-coplanar geometry to one Ce3+ and two equivalent Al3+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Ca2+, one Fe3+, one Al3+, and one Si4+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Ce3+, one Fe3+, and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Ca2+, one Ce3+, one Al3+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a trigonal non-coplanar geometry to one Fe3+ and two equivalent Al3+ atoms. In the tenth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Ca2+, two equivalent Al3+, and one Si4+ atom.« less
