The crystal structure described by LiAlSiH2O5 crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. Al(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(5) atom. Si(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2), one O(4), and one O(5) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(3) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Li(1), one Al(1), and one O(4) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Al(1), and one Si(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1), one H(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Si(1), and one O(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Al(1) and one Si(1) atom. is represented by the CIF card [CIF]
