# Is there a theoretical way to predict the coordination number a metal can have in a complex? [closed]

We know that metals can form complexes with different coordination numbers, but I was told that certain metals have a greater probability to have a certain coordination number.

But I was not able to find any such list that correlates a metal with its most favorable coordination number.

As an example, I guess $\ce{Fe^3+}$ forms complexes with coordination number 6, but can I actually predict the coordination number in a reaction or not?
