How are H20 and OH2 different?

 

[Vagrant]

I don't think they are different but my chemistry textbook uses OH2 in some complex entities. So I wanted to know if it was so because oxygen is the donor atom in the ligand.
But if it is so then why use H2O, when denoting water as a ligand in some cases?

 

[chemisttree]

There is no reason except to emphasize that the bonding occurs through the oxygen.

Thanks a lot for clearing my doubt.
