Materials Data on LiAlSiH2O5 by Materials Project
LiAlSiH2O5 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent AlO4 tetrahedra and corners with three equivalent SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.04 Å. Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with three equivalent LiO4 tetrahedra and corners with four equivalent SiO4 tetrahedra. There is two shorter (1.77 Å) and two longer (1.78 Å) Al–O bond length. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent LiO4 tetrahedra and corners with four equivalent AlO4 tetrahedra. There is one shorter (1.64 Å) and three longer (1.65 Å) Si–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Al3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Al3+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Al3+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Al3+, and one Si4+ atom.
