Rules for nomenclature of coordination compounds?

Okay, so what I know is, while writing their formulas, the ligands are listed alphabetically according to their symbols. Why is Dichloridobis (ethane-1, 2-diamine) Iron (III) chloride formulated as [Fe(en)2cl2]cl, then? Shouldn't Cl come before en?

Are the prefixes 'bis', 'tris' etc that we use as prefixes for polydendate ligand a ignored while deciding the alphabetical order?
