<br/><br/>Until recently, transplutonium elements were thought to be similar to their lanthanide predecessors which have primarily ionic interactions with surrounding atoms. However, the 5f/6d orbitals of these f elements have been shown to mix with or be degenerate with the 2p or 3p orbitals of lighter atoms generating covalent interactions. Therefore, the bonding in the mid actinides tend to have some degree of covalency. There has been progress made in probing the covalency with the heavier actinides in the Albrecht-Schmitt group with the borates, dipicolinic acid, and specifically the dithiocarbamate (DTC)/ phenanthroline (phen) systems. The tris DTC/phen system is interesting due to the counterintuitive soft sulfur donors as well as their ease of synthesis. Due to pi stacking interactions present in phen, this unique system can crystalize within minutes making the compound very suitable for characterization with the high emitting actinides. This inspired the synthesis of homoleptic pyrollidinedithiocarbamate complexes to probe An-S bonding. These structures are characterized by single crystal X-ray diffraction to investigate the An-S bond.<br/>
