This study aims to explore how positioning Group I or Group II metal ions in close proximity to transition metal ions influences their properties and reactivities. Several ditopic ligand systems have been synthesized and characterized. Each ligand system investigated contains two unique binding sites. One site within the ligand framework is designed specifically to incorporate a transition metal ion and the other site has been engineered to selectively bind an alkali or alkaline earth metal ion. The synthesis and characterization of the ligand systems will be presented. The ligand systems have been used to coordinate several first row transition metal ions including MnII, CoII, NiII and ZnII. The ability of these mononuclear transition metal complexes to bind Group I or Group II metal ions has been surveyed. The formation and characterization of these heterobimetallic complexes will be discussed and the properties of the mononuclear complexes will be compared to their heterobimetallic congeners.
