GaOOH crystallizes in the orthorhombic Fdd2 space group. Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing GaO6 pentagonal pyramids. H(1) is bonded in a distorted single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OGa4 tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ga(1) and one H(1) atom.
GaOOH crystallizes in the orthorhombic Fdd2 space group. Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing GaO6 pentagonal pyramids. There is one shorter (2.04 Å) and one longer (2.05 Å) Ga(1)-O(2) bond length. There are a spread of Ga(1)-O(1) bond distances ranging from 1.99-2.20 Å. H(1) is bonded in a distorted single-bond geometry to one O(2) atom. The H(1)-O(2) bond length is 0.98 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OGa4 tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ga(1) and one H(1) atom.
