Materials Data on Ba(GaH)2 by Materials Project
Ba(GaH)2 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Ba(GaH)2 sheet oriented in the (0, 0, 1) direction. Ba is bonded in a distorted hexagonal planar geometry to six equivalent H atoms. All Ba–H bond lengths are 2.71 Å. Ga is bonded in a single-bond geometry to one H atom. The Ga–H bond length is 1.69 Å. H is bonded to three equivalent Ba and one Ga atom to form a mixture of distorted corner and edge-sharing HBa3Ga tetrahedra.
