# Complex species doubt

1. The problem statement, all variables and given/known data
Are $$H_{2}O$$ and $$OH_2$$ same species when used as ligand in complex entity?
Can these be used interchangeably?

2. Relevant equations

3. The attempt at a solution

How are H20 and OH2 different?

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?

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

Thanks a lot for clearing my doubt.
