6 Ligand Nomenclature

7 18 Electron Rule: Examples
Cr(CO)6 (5-C5H5)Fe(CO)2Cl [Re(CO)5(PF3)]+ PF3 is neutral

8 18 Electron Rule

9 18 Electron Rule: Why? Use an octahedral example
Happens with strong -donor and/or strong -backbonding ligands. Why not fewer e-’s? Why not more e-’s?

10 16/18 Electron Rule: Important 16-e- square planar examples; all
high field d8

11

12 18 Electron Rule: Many, many classical complexes don’t follow it.
[Zn(en)3]2+ Cr(NH3)63+
