AlOOH crystallizes in the orthorhombic Pnnm space group. Al(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 53°. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to three equivalent Al(1) and one H(1) atom to form a mixture of distorted corner and edge-sharing OAl3H tetrahedra.
AlOOH crystallizes in the orthorhombic Pnnm space group. Al(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are four shorter (1.93 Å) and two longer (1.96 Å) Al(1)-O(1) bond lengths. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both H(1)-O(1) bond lengths are 1.21 Å. O(1) is bonded to three equivalent Al(1) and one H(1) atom to form a mixture of distorted corner and edge-sharing OAl3H tetrahedra.
