Bimetallic Centers With Open Coordination Sites And Magnetic Nanocomposites For Water Remediation, Karen Ventura

Open Access Theses & Dissertations

The development of effective, renewable and environmentally friendly energy sources is essential to supply the growing global energy demands. The use of fossil fuels to fulfill those energy demands have led to the increase of greenhouse gases and water contamination. The extraction of oil and gas requires a large amount of pressurized water, resulting in contaminated water as a byproduct. Meanwhile, ensuring access to clean water is one of the greatest global challenges of this century.

The following study is presented in three sections. In the first section, a bimetallic system with open coordination sites that can be used as …

On The Path To Multi-Electron Redox Chemistry With Bimetallic Systems, Nathalie Metta

Open Access Theses & Dissertations

The following study is presented in two sections, in the first, a novel digold (II) complex with semi-bridging chlorides supported by two bulky formamidinates was synthesized for the purpose of studying late-transition metal multi-electron redox chemistry. Electrochemical analysis shows one non-reversible reduction. Although the electrochemistry of this complex is restricted, the compound shows interesting electronic properties. The crystal structure reveals a geometry distortion of the Au2ï?­-Cl2 core. The coupling of an unoccupied orbital and an occupied orbital through a vibrational mode, causes a distortion in the geometry of the molecule lowering the D2h symmetry to C2h. This is an example …
