The crystal structure described by RbGaH4 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to one H(1), one H(2), and six equivalent H(3) atoms. Ga(1) is bonded in a tetrahedral geometry to one H(1), one H(2), and two equivalent H(3) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to one Rb(1) and one Ga(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Rb(1) and one Ga(1) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Ga(1) atom. is represented by the CIF file [CIF]
