Abstract

Al2Si4O11 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Al2Si4O11 sheet oriented in the (0, 0, 1) direction. Al3+ is bonded to five O2- atoms to form AlO5 trigonal bipyramids that share corners with four SiO4 tetrahedra, a cornercorner with one AlO5 trigonal bipyramid, and edges with two equivalent AlO5 trigonal bipyramids. There are a spread of Al–O bond distances ranging from 1.68–1.97 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent SiO4 tetrahedra and corners with two equivalent AlO5 trigonal bipyramids. There are a spread of Si–O bond distances ranging from 1.63–1.65 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent SiO4 tetrahedra and corners with two equivalent AlO5 trigonal bipyramids. There are a spread of Si–O bond distances ranging from 1.63–1.65 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Al3+ atoms.
