dc.description.abstractAssembly of heterobimetallic complexes is challenging due to the propensity of ditopic ligands to bind metals unselectively. This challenge is exacerbated in situations in which two redox-inactive metals are to be coordinated within one ligand framework, as such metals can bind in a variety of coordination environments. In this thesis, the preparation and isolation of four heterobimetallic complexes of zinc, a redox-inactive first-row transition metal, with a range of other redox-inactive Lewis acidic metals (Na+, Ca2+, Nd3+, and Y3+) are reported. The complexes were prepared via a divergent route in which a common monometallic zinc complex featuring a crown-ether-like site within a macrocyclic structure was selectively metallated with triflate salts of sodium, calcium, neodymium, and yttrium. One-dimensional 1H and two-dimensional 1H–1H Correlation Spectroscopy (COSY) Nuclear Magnetic Resonance (NMR) studies provide robust support for synthesis of the target heterobimetallic compounds. Single crystals suitable for X-ray diffraction analysis were grown of the [Zn,Nd] complex, revealing the expected atomic connectivity within the macrocyclic framework. In the solid state, the zinc center is five-coordinate, with a terminal acetonitrile ligand; this finding contrasts with the structure of the analogous [Ni,Nd] complex that instead features a four-coordinate nickel center. These results are discussed in the context of developing model compounds for study of the spectroscopic and electrochemical properties of heterobimetallic complexes containing redox-inactive Lewis acids.en_US
