摘要：

Advancing our understanding of the minor actinides (Am, Cm) versus lanthanides is key for developing advanced nuclear-fuel cycles. Herein, we describe the preparation of (NBu4)Am[S2P((Bu2C12H6)-Bu-t)](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)angstrom, 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.
