Find the formula for sodium bisoxalato(diaqua)ferrate (III).

I was confused as to why (OH)2 came before (C2O4)2 in the formula, isn't it alphabetical by the symbol?
Also, what do the parenthesis in the name mean?

[Amy Lefley 1J]

I was confused by this too. I think the alphabetical rule only applies when you are naming the complex, not writing its formula, so I think the ligand can be in any order. In terms of the parentheses, I am not completely sure - maybe to make the complex name easier to read?

Water is "aqua", which starts with "A."

[mbaker4E]

I think the parenthesis are just to separate the two ligands.
