Homework Help: Fe-N bond!

  1. Mar 26, 2006 #1
    I've been searching far and wide and simply cannot find any info on the BOND ENERGY of a Fe- N coordinate-covalent bond, like that found in the heme group of haemoglobin.


    it looks like this:
    ....... N
    ....... |
    N -- Fe2+ -- N
    ....... |
    ....... N

    The Fe2+ ion also has 2 coordination sites perpendicular to that plane.

    Where can I possibly find the bond energy/length of those coordinate covalent bonds?
