Mercury(II) hydroxide molecules have been prepared upon mercury arc lamp irradiation of Hg, H2, and O2 mixtures in solid neon and argon. The strongest three infrared absorptions are identified through isotopic substitution (D2, HD, 18O2,16O 18O) and comparison to frequencies from DFT calculations. The isolated Hg(OH)2 molecule is stable and has a linear O-Hg-O linkage in a C2 structure with an 86° dihedral angle. However, in aqueous solution Hg2+ and 2OH- may form an Hg(OH)2 intermediate, which eliminates water and precipitates solid HgO: The solid Hg(OH)2 compound is not known.
