Yes I think I saw in another chemistry community post that when H2O is within the coordination compound, it's name is aqua. For example, in the coordination compound [CrCl3(NH3)2(OH2)]+ , H2O would be referred to as aqua. When outside of the bracket, H2O is referred to as hydrate. Honestly, I'm not sure if there are any other differing names.

Yes, if the water is acting as a ligand within the coordination sphere (inside the brackets) it is referred to as 'aqua.' When it is outside the coordination sphere it is 'hydrate' (with the appropriate prefix.)
