Materials Data on Na3Al3Si3O16 by Materials Project
Na3Al3Si3O16 crystallizes in the trigonal R3c space group. The structure is three-dimensional. Na is bonded in a 3-coordinate geometry to six O atoms. There are a spread of Na–O bond distances ranging from 2.35–2.67 Å. Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with four equivalent SiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.74–1.77 Å. Si is bonded to four O atoms to form SiO4 tetrahedra that share corners with four equivalent AlO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.64 Å. There are six inequivalent O sites. In the first O site, O is bonded in a distorted hexagonal planar geometry to three equivalent Na and three equivalent O atoms. All O–O bond lengths are 1.75 Å. In the second O site, O is bonded in a 3-coordinate geometry to two equivalent Na and one O atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Al and one Si atom. In the fourth O site, O is bonded in a distorted trigonal planar geometry to one Na, one Al, and one Si atom. In the fifth O site, O is bonded in a distorted trigonal planar geometry to one Na, one Al, and one Si atom. In the sixth O site, O is bonded in a distorted trigonal planar geometry to one Na, one Al, and one Si atom.
