The material described by AlOOH crystallizes in the orthorhombic Cmc2_1 space group. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 21°. H(1) is bonded in a distorted single-bond geometry to two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Al(1) atoms to form a mixture of edge and corner-sharing OAl4 trigonal pyramids. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Al(1) and two equivalent H(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
