Although ligand field stabilization dominates the coordination chemistry of the transition metals, these effects are absent for other metal ions that do not use valence d orbitals for bonding, such as the alkali, alkaline earth, and lanthanide ions.  The bonding interactions of these latter ions are instead dictated by electrostatic interactions, the strength of which scales inversely with ionic radii. As such, large s-, p-, and f-block ions form coordination complexes of low thermodynamic and kinetic stability compared to their smaller counterparts. In this presentation, we discuss our efforts to develop chelating agents that can stabilize these large ions. Furthermore, we describe our use of these chelating agents for various applications in imaging, nuclear medicine, and industrial processes. This presentation underlines both the fundamental coordination chemistry principles and practical application considerations for this class of ions.  <br/>
