As with Part II, Part III of the book concludes with a complete worked example which brings together all the concepts and techniques described in earlier sections. The molecule which forms the focus of this chapter is ferrocene, (C5H5)2Fe, the parent in a family of so called “sandwich” compounds and perhaps the most studied and exploited organometallic compound known (Fig. Error! Reference source not found..1).
10.1 Ferrocene, (a) showing delocalisation within the cyclopentadienyl rings, (b) the pz orbitals on carbon used in bonding and (c) the location of key symmetry elements in D5d.
Part III began with a look at the simple problem ...
