Materials Data on SrGaSiH by Materials Project
SrGaSiH crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Sr2+ is bonded in a distorted trigonal planar geometry to three equivalent Si4- and three equivalent H1- atoms. All Sr–Si bond lengths are 3.28 Å. All Sr–H bond lengths are 2.47 Å. Ga3+ is bonded in a distorted single-bond geometry to three equivalent Si4- and one H1- atom. All Ga–Si bond lengths are 2.48 Å. The Ga–H bond length is 1.78 Å. Si4- is bonded in a 6-coordinate geometry to three equivalent Sr2+ and three equivalent Ga3+ atoms. H1- is bonded to three equivalent Sr2+ and one Ga3+ atom to form distorted corner-sharing HSr3Ga trigonal pyramids.
