Materials Data on SrAlSiH by Materials Project
Abstract
SrAlSiH crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Sr2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si4- and three equivalent H1- atoms. All Sr–Si bond lengths are 3.29 Å. All Sr–H bond lengths are 2.50 Å. Al3+ is bonded in a distorted single-bond geometry to three equivalent Si4- and one H1- atom. All Al–Si bond lengths are 2.49 Å. The Al–H bond length is 1.75 Å. Si4- is bonded in a 3-coordinate geometry to three equivalent Sr2+ and three equivalent Al3+ atoms. H1- is bonded to three equivalent Sr2+ and one Al3+ atom to form distorted corner-sharing HSr3Al tetrahedra.
