Recent advances in the growing field of organometallic transuranic chemistry has lead to a further understanding of bonding and electronic properties in the actinides. A reaction between Cp′3M (Cp′ = trimethylsilylcyclopentadienide) and 4,4′−bpy (4,4′−bipyridine) has yielded a series of organometallic multinuclear transuranic complexes, (Cp′3M)2(μ−4,4′−bpy), displaying surprisingly ionic M−N bonding. These systems provide some of the first structural characterization M−C bonds in transplutonium elements, as well as spectroscopic properties distinctive to organometallic f-block molecules. Structural and spectroscopic characterization of an organometallic multinuclear transuranic system, (Cp′3M)2(μ−4,4′−bpy), as well as the challenges of characterizing air sensitive, radioactive compounds is discussed.
