  • Molecular and crystal structures of uranyl nitrate complexes with N-alkylated-2Pyrrolidone Derivatives : Design and optimization of promising precipitant for uranyl ion
    Crystal Growth & Design, 2008
    Co-Authors: Koichiro Takao, Kyoko Noda, Yasuji Morita, Kenji Nishimura, Yasuhisa Ikeda

    Abstract:

    Molecular and crystal structures of UO2(NO3)2(NRP)2 (NRP = N-alkylated 2Pyrrolidone Derivative) have been investigated by using single crystal X-ray analysis. All UO2(NO3)2(NRP)2 complexes have typical structural properties of UO2(NO2)2(L)2 (L = unidentate ligand), i.e., hexagonal-bipyramidal geometry, two NRP and two NO3− located in trans positions in an equatorial plane of the uranyl moiety, U═Oyl ≃ 1.76 A, U−ONRP = 2.38−2.41 A, U−ONO3 = 2.50−2.54 A, and a bond angle between the U−ONRP bond and the carbonyl group of NRP (ca. 135°). In the crystals of the uranyl nitrate complexes with N-n-propyl-2Pyrrolidone (L3a) and N-iso-propyl-2Pyrrolidone (L3b), polymorphism between monoclinic (293 K) and triclinic forms (173 K) was observed, indicating the presence of significant voids in the crystal lattices of these compounds. From this result, an approach for construction of efficient packing of UO2(NO2)2(NRP)2 was proposed, i.e., the efficient packing would be built up when an alkyl chain of NRP fills the vo…
