“…Therefore, complexation by nitrates can easily occur during desolvation, when coordinating solvent molecules are stripped away. In the crystal structure of Rb[(UO 2 )(NO 3 ) 3 ], each nitrate group chelates uranyl in a bidentate fashion, and the conformation around U(VI) is hexagonal bipyramid [45]. The coordination of [(UO 2 )(NO 3 ) 3 ] Ϫ in the gasphase is presumed to be similar.…”

Electrospray ionization (ESI) of uranyl nitrate solutions generates a wide variety of positively and negatively charged ions, including complex adducts of uranyl ions with methoxy, hydroxy, and nitrate ligands. In the positive ion mode, ions detected by Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry are sensitive to instrumental tuning parameters such as quadrupole operating frequency and trapping time. Positive ions correspond to oligomeric uranyl nitrate species that can be characterized as having a general formula of

“…It is seen that rl and r2 are always greater than r3 by about 0.05/k, while 01 and 02 are greater than 03 by about 6 ° . Ferraro (1960) (Barclay, Sabine & Taylor, 1965), where there is no hydrogen bonding, it seems probable that the effect is largely due to the interaction with the metal atom. This is one of the mechanisms proposed by Ferraro & Walker (1965).…”

“…In Table 4 we have summarized the distances and angles found in the nitrate groups in thorium nitrate pentahydrate, uranyl nitrate hexahydrate , rubidium uranyl nitrate (Barclay, Sabine & Taylor, 1965) and cerium magnesium nitrate hydrate (Zalkin, Forrester & Templeton, 1963). The latter study is by X-ray diffraction, while the others are neutron diffraction studies.…”

The crystal structure of thorium nitrate pentahydrate, Th(NO3)4.5H20, has been determined by neutron diffraction. It is orthorhombic, space group Fdd2, with a = 11.191 + 0.007/~,, b = 22-889 + 0.015/~ and c= 10.579+0.007/~,. A total of 1642 independent reflections with 20 < 122 ° 0~= 1.065/~) were used. The structure was solved from the three-dimensional Patterson function and refined by the full-matrix least-squares method to R = 4.3 % with the use of a statistical weighting scheme.Eleven oxygen atoms are bound to the thorium atom, eight being from four bidentate nitrate groups and the other three from water molecules. The Th-O (water) distances, 2-438 and 2.473/~,, are shorter than the Th-O (nitrate) distances, 2-528 to 2.618/1. The nitrate groups are planar and the N-O distances are found to be significantly different within the group. The structure is tied together by a simple hydrogen-bond scheme in which the hydrogen bonds are either 'strong' water-water hydrogen bonds (2-70/~) or 'weak' water-nitrate oxygen hydrogen bonds (2.90-2.95 •).

“…The oxalate groups form stable five-membered rings with the uranium atom, unlike the four-membered rings formed in the acetato, nitrato and carbonato complexes ofuranyl (Zachariasen & Plettinger, 1959;Barclay, Sabine & Taylor, 1965;Mazzi & Rinaldi, 1961). Very short 'biting' distances in the latter ligands lead to planar hexagonal coordination.…”

Uranyl oxalate trihydrate, UOzCzO4.3H20, crystals are monoclinic with lattice parameters a = 5.623 (5), b=17.065 (2), c=9.451 (3)/~ and ,8=98.74 (1) °. The space group is P21/C with Z=4. 513 visually estimated reflexions were corrected for absorption and the structure refined by Fourier and least-squares methods to R = 0"079. Each uranium atom exists as a linear (O-U-O) 2+ ion with five secondary oxygen atoms coordinated to it in a perpendicular plane. The average distances are U-O~= 1-63 (4) and U-On = 2"49 (4)/~. The oxalate groups are planar and tetradentate, each bridging two uranyl ions. Only one water molecule is coordinated to the uranium atom. The structure is consistent with the thermal behaviour of the compound.
