Abstract
Characterizing how actinide properties change across the f-element series is critical for improving predictive capabilities and solving many nuclear problems facing our society. Unfortunately, it is difficult to make direct comparisons across the 5f-element series because so little is known about trans-plutonium elements. Results described herein help to address this issue through isolation of An(S2CNEt2)3(N2C12H8) (Am, Cm, and Cf). These findings included the first single crystal X-ray diffraction measurements of Cm-S (mean of 2.86 ± 0.04 Å) and Cf-S (mean of 2.84 ± 0.04 Å) bond distances. Furthermore, they highlight the potential of An(S2CNEt2)3(N2C12H8) for providing a test bed for comparative analyses of actinide versus lanthanide bonding interactions.

We gratefully recognize the Heavy Element Chemistry Program at LANL by the Division of Chemical Sciences, Geosciences, and Biosciences, Office of Basic Energy Sciences, U.S. Department of Energy and the U.S. Department of Energy for funding the synthesis and characterization of the Cm (S2CNEt2)3(N2C12H8) complex. Los Alamos National Laboratory is operated by Los Alamos National Security, LLC, for the National Nuclear Security Administration of U.S. Department of Energy (contract DE-AC52-06NA25396). We additionally thank the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, Heavy Elements Chemistry Program, under Award Numbers DE-FG02-13ER16414 for the synthesis and characterization of Cf(S2CNEt2)3(N2C12H8) (Albrecht-Schmitt, Galley, Alstine). The synthesis of Am (S2CNEt2)3(N2C12H8), the computational work for the M(S2CNEt2)3(ligand) compounds, and the Cm and Cf reprocessing efforts were supported as part of the Center for Actinide Science and Technology (CAST) an Energy Frontier Research Center (EFRC) funded by the U.S. Department of Energy (DOE), Office of Science, Basic Energy Sciences (BES), under Award Number DE-SC0016568. In addition, portions of this work were supported by postdoctoral fellowships from the Glenn T. Seaborg Institute (Ferrier, Su) and the LDRD office, named fellowship program; Hoffman Distinguished Postdoctoral Fellowship (Cary).
