The class of materials known as ionic liquids (ILs) is now being used for a wide variety of applications due to reports of their excellent properties such as superior solvating effects, low viscosity, high conductivity, and high thermal/electrochemical stability. However, the structure and magnetic behavior of metal complexes with multidentate ligands such as dicyanamide are not completely understood yet due to the inability to obtain crystalline materials from ionic liquids. This study focuses on trapping out complex metal-ligand structures in glass forming ILs with unique properties distinct from what is observed in bulk materials. In particular, the dicyanamide complexes of cobalt in phosphonium ILs are observed through differential scanning calorimetry, infrared spectroscopy, and UV-VIS spectroscopy, along with their magnetic properties using magnetic susceptibility measurements. The structure property relationships in these materials could potentially allow for better control of structure formation and resulting properties, as well as to allow for further understanding the emergent phenomena as they relate to growing structures.<br/>
