Cyclooctatetraene-Based Lanthanide and Alkali Metal Complexes: Synthesis, Properties and Reactivity

This thesis explores the synthesis, coordination chemistry, and properties of lanthanides and alkali metal complexes, with particular emphasis on phosphine-functionalized Cot and ansa-bridged Cot systems. Their coordination behavior Cot bease ligand invistigated with alkali metals and lanthanides to access structurally diverse sandwich, half-sandwich, binuclear, and multimetallic complexes. The study further examines heterobimetallic cerium(IV) sandwich complexes and the reactivity of binuclear lanthanide systems. These investigations provide insights into the influence of phosphine substituted Cot on molecular structure, bonding, photophysical behavior, and magnetic properties, contributing to the development of novel organometallic architectures with potential relevance to coordination chemistry and advanced functional materials.
