CsGaH4 crystallizes in the orthorhombic Pnma space group. Cs(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 single-bond geometry to one Cs(1) and one Ga(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to one Cs(1) and one Ga(1) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Ga(1) atom.
