In previous literature, it has been proposed that catalysts efficiently perform catalysis, especially C-H activation, because of their high spin orbit coupling constant. The canonical model of these catalysts uses a heavy central metal atom and light donor ligands to form the catalyst. However, the heavy metal tends to be comprised of high cost metals such as platinum, gold and ruthenium. Therefore, this project uses light 3d metals as the central metal and low cost, heavy donor ligands to contribute spin orbit coupling into the metal center. The heavy donor ligands utilize antimony for its low cost but high spin orbit coupling constant. Three substituents of varying steric and electron donating/withdrawing properties are attached to the antimony metal center. It has been observed for copper metal centers that the cone angle of these substituents affects whether the ligand dimerizes or forms a cubic structure with luminescent properties. Furthermore, this project delves into the steric and electronic properties of the ligands to determine the dimer versus cube formations and the luminescent properties of the cubic structures.
