RbGaH2 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent H(2) atoms. Ga(1) is bonded in a distorted water-like geometry to one H(1) and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and one Ga(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Ga(1) atom.
RbGaH2 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent H(2) atoms. There are a spread of Rb(1)-H(1) bond distances ranging from 2.93-3.14 Å. There are two shorter (3.01 Å) and two longer (3.05 Å) Rb(1)-H(2) bond lengths. Ga(1) is bonded in a distorted water-like geometry to one H(1) and one H(2) atom. The Ga(1)-H(1) bond length is 1.66 Å. The Ga(1)-H(2) bond length is 1.65 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and one Ga(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Ga(1) atom.
