Title: Comparing the 2,2'-Biphenylenedithiophosphinate Binding of Americium with Neodymium and Europium

Advancing our understanding of the minor actinides (Am, Cm) versus lanthanides is key for developing advanced nuclear-fuel cycles. Here in this paper, we describe the preparation of (NBu 4)Am[S 2P( tBu 2C 12H 6)] 4 and two isomorphous lanthanide complexes, namely one with a similar ionic radius (i.e., Nd III) and an isoelectronic one (Eu III). The results include the first measurement of an Am-S bond length, with a mean value of 2.921(9) Å, by single-crystal X-ray diffraction. Comparison with the Eu III and Nd III complexes revealed subtle electronic differences between the complexes of Am III and the lanthanides.
