Materials Data on HAuO2 by Materials Project
AuOOH crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two AuOOH sheets oriented in the (1, 0, 0) direction. Au3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Au–O bond lengths are 2.04 Å. H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Au3+ and one H1+ atom.
