Electrometric Determination of Stability Constants of Uranyl-Chloride and Uranyl-Nitrate Complexes with pCl-Stat

Uranyl sequestration: synthesis and structural characterization of uranyl complexes with a tetradentate methylterephthalamide ligand.

Uranyl complexes of a bis(methylterephthalamide) ligand (LH(4)) have been synthesized and characterized by X-ray crystallography. The structure is an unexpected [Me(4)N](8)[L(UO(2))](4) tetramer, formed via coordination of the two MeTAM units of L to two uranyl moieties. Addition of KOH to the tetramer gave the corresponding monomeric uranyl methoxide species [Me(4)N]K(2)[LUO(2)(OMe)].

Infrared spectroscopy of discrete uranyl anion complexes.

The Free-Electron Laser for Infrared Experiments (FELIX) was used to study the wavelength-resolved multiple photon photodissociation of discrete, gas-phase uranyl (UO22+) complexes containing a single anionic ligand (A), with or without ligated solvent molecules (S). The uranyl antisymmetric and symmetric stretching frequencies were measured for complexes with general formula [UO2A(S)n]+, where...

The Uranyl Nitrate - Water System Above 60 °

Easy access to stable pentavalent uranyl complexes.

Reaction of UO2I2(THF)3 with 1 molar equivalent of KC5R5 (R = H, Me) in pyridine led to the uranyl(V) compound {[UO2(Py)5][KI2(Py)2]}(infinity), which is an infinite 1D polymer in its crystalline form; the UO2X(THF)n (X = I, OSO2CF3) complexes were obtained by reduction of their U(VI) parents with TlC5H5 or KC5R5 in THF.

The Mechanism of Acute Renal Failure after Uranyl Nitrate ROLAND

Portions of this work were presented at the Annual Meeting of The American Federation for Clinical Research, Atlantic City, N. J., 5 May 1974. Received for publication 21 June 1974 and in revised form 18 November 1974. dose UN (0.047±0.013) and high dose (0.024±0.003 nVs/g kidney wt/mm Hg). Therefore UN decreases GFR by two mechanisms: (a) tubular damage leading to back-diffusion of solutes and...
