Abstract

NaAl3(SiO4)3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Na is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are a spread of Na–O bond distances ranging from 2.39–2.78 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded to six O atoms to form distorted AlO6 octahedra that share a cornercorner with one AlO4 tetrahedra, corners with three SiO4 tetrahedra, and edges with three equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.84–1.99 Å. In the second Al site, Al is bonded to six O atoms to form distorted AlO6 octahedra that share a cornercorner with one AlO4 tetrahedra, corners with three SiO4 tetrahedra, and edges with three equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.80–2.00 Å. In the third Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with two AlO6 octahedra and corners with three equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of Al–O bond distances ranging from 1.75–1.78 Å. There are three inequivalent Si sites. In the firstmore »« less
