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

18 Electron Rule

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?

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