The crystal structures of americium species containing a common multifunctional phosphine oxide ligand, reported for its ability to extract f elements from acidic solutions, namely, 2,6-[Ph2P­(O)­CH2]2C5H3–NO, L, were finally determined after over three decades of separations studies involving these species and their surrogates. The molecular compounds Am­(L)­(NO3)3, Am 1:1, and [Am­(L)2(NO3)]­[2­(NO3)], Am 2:1, along with their neodymium and europium analogues, were synthesized and characterized using single-crystal X-ray crystallography, attenuated total reflectance Fourier transform infrared spectroscopy, and luminescence spectroscopy to provide a comprehensive comparison with new and known analogous complexes.
