This thesis explores 4,5-diazafluorenyl derivatives as binucleating ligands for the syntheses of heterobimetallic complexes. The 4,5-diazafluorenide (L-) ligand contains two coordination sites: a Cp moiety and two N-donors. L- was used to construct PtII-CuI and PtII-RuII heterobimetallic complexes. Various modifications have been made to the L- framework to alter the regioselectivity. A pendent phosphine was arm attached to the methylene linker to form 9-(2-(diphenylphosphino)ethyl)-4,5-diazafluorenide (Lp-) and provides a P,C-chelate to anchor metals to the C-donor on the L- backbone. Lp- was used to synthesize PtII-CuI complexes and dinuclear RuII complexes. Bulky mesityl groups were installed ortho- to the N-donors to form 3,6-dimesityl-4,5-diazafluorenide (LMes-). The LMes- derivative provides steric protection that prevents bulky metal fragments from binding to the N-donors. LMes- was used to construct a series of RuII-M complexes (M = FeII, CoII, PtII, CuI) where the metals span from group 8 to 11.
