InOOH crystallizes in the orthorhombic Pmn2_1 space group. In(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 54-57°. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent In(1) and one H(1) atom to form distorted corner-sharing OIn3H tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent In(1) and one H(1) atom.
InOOH crystallizes in the orthorhombic Pmn2_1 space group. In(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing InO6 octahedra. The corner-sharing octahedral tilt angles range from 54-57°. All In(1)-O(1) bond lengths are 2.14 Å. There are two shorter (2.24 Å) and one longer (2.25 Å) In(1)-O(2) bond length. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. The H(1)-O(1) bond length is 1.53 Å. The H(1)-O(2) bond length is 1.03 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent In(1) and one H(1) atom to form distorted corner-sharing OIn3H tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent In(1) and one H(1) atom.
