Materials Data on CaAl2Si3O13 by Materials Project
Abstract
CaAl2Si3O13 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Ca is bonded in a 5-coordinate geometry to six O atoms. There are a spread of Ca–O bond distances ranging from 2.35–3.05 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra. There is three shorter (1.75 Å) and one longer (1.79 Å) Al–O bond length. In the second Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.76–1.79 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share corners with two AlO4 tetrahedra and corners with two SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.60–1.66 Å. In the second Si site, Si is bonded to four O atoms to form SiO4 tetrahedra that share a cornercorner with one SiO4 tetrahedra and corners with three AlO4 tetrahedra. There are a spread of Si–O bond distances ranging frommore »
