OH is a hydroxyl radical (as in sodium hydroxide) or the alcohol functional group.
HgOH would be called mercury(I) hydroxide or mercurous hydroxide. This is a compound that is not well characterised, in other words it is reported by chemists but (as far as I know) the existence of the solid compound has not been proven- e.g. by x-ray crystallography. Some authors say it only exists in solution. It would contain the diatomic Hg22+ ion and the formula would be written Hg2(OH)2.
The color of mercury(II) hydroxide is tan-brown.
The formula for hydrogen hydroxide is H2O.
