The work described in this thesis is focused on the use of novel axially chiral ligands as building blocks for interesting coordination structures, with particular emphasis on constructing helical coordination complexes. Ligands were designed in light of the preferred coordination geometries of specific metals in order to attempt to control the final structures. The synthesis of a new series of binaphthyl-based amide and imine ligands was developed, and their coordination to palladium, platinum, nickel, rhenium, ruthenium, and cobalt investigated. In addition, the synthesis of biphenanthroline and biaryl ligand systems was explored and the chemistry of their precursors examined. Finally, a novel range of biquinazolinones were synthesised and their behaviour as ligands was probed. The previously unreported coordination chemistry of this new class of axially chiral ligands is demonstrated by their complexation with rhenium, palladium and ruthenium. The first examples of crystal structures of biquinazolinone metal complexes are presented in this thesis.
