Materials Data on Sr(GaH)2 by Materials Project
Sr(GaH)2 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Sr(GaH)2 sheet oriented in the (0, 0, 1) direction. Sr is bonded in a hexagonal planar geometry to six equivalent H atoms. All Sr–H bond lengths are 2.59 Å. Ga is bonded in a single-bond geometry to one H atom. The Ga–H bond length is 1.70 Å. H is bonded to three equivalent Sr and one Ga atom to form a mixture of distorted corner and edge-sharing HSr3Ga trigonal pyramids.
