Abstract

We report the small-scale synthesis, isolated yield, single-crystal X-ray structure, ¹ H NMR solution spectroscopy /solid-state UV/Vis-nIR spectroscopy, and density functional theory (DFT)/ab initio wave function theory calculations on an Am³⁺ organometallic complex, [Am(C₅ Me₄ H)₃ ] (1). This constitutes the first quantitative data on Am-C bonding in a molecular species.

Keywords: actinides; americium; cyclopentadienyl ligands; organometallic complexes; structure elucidation.
