# Do coordination complexes with stronger ligands form more stable complexes?

I read that chelate complexes generally are more stable than monodentate complexes. However, I noticed that in the case of $$\ce{[Fe(CN)6]^3-}$$ and $$\ce{[Fe(en)3]^3+}$$, this is not observed as the former is more stable. Why is this so?
