The structure described by SrGaH5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 9-coordinate geometry to two equivalent H(4), three equivalent H(3), and four equivalent H(1) atoms. Ga(1) is bonded in a tetrahedral geometry to one H(2), one H(4), and two equivalent H(1) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Ga(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Ga(1) atom. In the third H site, H(3) is bonded in a distorted trigonal planar geometry to three equivalent Sr(1) atoms. In the fourth H site, H(4) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Ga(1) atom. is represented by the CIF file [CIF]
