The unique ability to tune the physical and solvent properties of ionic liquids based on the cation and anion chosen is of great interest in the area of crystallizations. Not only do the interactions between the cation and anion influence the crystal structure but also the interactions between the IL, metal, and ligand can influence the resulting crystal structures. Based on the interactions in these complex solvent systems, the crystals produced can be similar to those from traditional solvents or completely new crystal structures. This inherent property of ionic liquids presents an allotment of unknown affects to crystal growth and structure, which can only be probed through experimentation. This presentation will explore a new class of anions, azolates, and the cation-anion interactions in these ILs. Also recent results from crystal engineering in ILs will be discussed. The effects of close interactions between metals and ligands will be determined for a subset of crystal structures grown in ionic liquids. It is our goal, through experimentation, to better understand the presently little known effects of these solvents on crystal growth.
