Physicochemical Characterization and Antimicrobial Properties of Lanthanide Nitrates in Dilute Aqueous Solutions.

This work presents the results of studying dilute aqueous solutions of commercial (NO) · HO salts with = Ce-Lu using X-ray diffraction (XRD), IR spectroscopy, X-ray absorption spectroscopy (XAS: EXAFS/XANES), and pH measurements. As a reference point, XRD and XAS measurements for characterized (NO) · HO microcrystalline powder samples were performed. The local structure of -nitrate complexes in 20 mM (NO) · HO aqueous solution was studied under total external reflection conditions and EXAFS geometry was applied to obtain high-quality EXAFS data for solutions with low concentrations of ions.

Synchrotron powder diffraction in a systematic study of 4'-[2-(tosylamino)benzylideneamino]-2,3-benzo-15-crown-5 complexes.

The crystal structures of two compounds, CuL(2) and LiNCS.HL [HL = 4'-[2-(tosylamino)benzylideneamino]-2,3-benzo-15-crown-5], have been determined from synchrotron powder diffraction data. Both compounds crystallize in the monoclinic space group P2(1)/c and with one molecule in the asymmetric unit.
