Incorporation of alkaline earth metals into electronic thin films through Metal Organic Chemical Vapor Deposition (MOCVD) requires volatile and stable precursor sources. The large diameter of the heavy alkaline earth metals increases aggregation tendencies, thus decreasing the volatility of the compounds. Recent work in our laboratory has demonstrated the effectiveness of weak metal ligand interaction in providing coordinative steric saturation, thus affording an attractive strategy to control aggregation behavior. The effectiveness of both metal-fluorine and metal-π interactions was demonstrated. We here introduce a ligand system with both capabilities to explore the propensity for each of these modes of metal stabilization. This poster provides an overview of the structural chemistry of different alkaline earth metals analyzing the nature and degree of non-covalent interactions to provide critical information towards controlling the physical properties of these metals.
