Materials Data on Na4Al3(SiO4)3 by Materials Project

Abstract

Na4Al3(SiO4)3 crystallizes in the cubic P-43n space group. The structure is three-dimensional. Na is bonded in a trigonal non-coplanar geometry to three equivalent O atoms. All Na–O bond lengths are 2.37 Å. Al is bonded to four equivalent O atoms to form AlO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra. All Al–O bond lengths are 1.76 Å. Si is bonded to four equivalent O atoms to form SiO4 tetrahedra that share corners with four equivalent AlO4 tetrahedra. All Si–O bond lengths are 1.64 Å. O is bonded in a distorted trigonal planar geometry to one Na, one Al, and one Si atom.
