Title: Materials Data on CaAl4(SiO3)8 by Materials Project

Abstract

Ca(Al(SiO3)2)4 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one calcium molecule and one Al(SiO3)2 sheet oriented in the (0, 0, 1) direction. In the Al(SiO3)2 sheet, there are four inequivalent Al sites. In the first Al site, Al is bonded to six O atoms to form AlO6 octahedra that share corners with four SiO4 tetrahedra and edges with three AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.87–1.96 Å. In the second Al site, Al is bonded to six O atoms to form AlO6 octahedra that share corners with four SiO4 tetrahedra and edges with three AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.86–1.95 Å. In the third Al site, Al is bonded to six O atoms to form AlO6 octahedra that share corners with four SiO4 tetrahedra and edges with three AlO6 octahedra.
