Abstract:
The synthesis of tetravalent thorium and uranium complexes with the phosphaazaallene moiety, [N(tBu)C=P(C6H5)]2−, is described. The reaction of the bis(phosphido) complexes, (C5Me5)2An[P(C6H5)(SiMe3)]2, An = Th, U, with two equivalents of tBuNC produces (C5Me5)2An(CNtBu)[η2-(N,C)-N(tBu)C=P(C6H5)] with concomitant formation of P(SiMe3)2(C6H5) via silyl migration. These complexes are characterized by NMR and IR spectroscopy, as well as structurally determined using X-ray crystallography.

Few complexes of inner transition metals [Th(IV), Ce(IV), Nd(III), Gd(III)] have been synthesized by reacting their metal salts with lansoprazole, 2-([3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl]methylsulfinyl)-1H-benzoimidazole and cytosine. All the complexes were synthesized in ethanolic medium. The yield percentage rangs from 80 to 90%. The complexes are coloured solids. The complexes were characterized through elemental analyses, conductance measurements, and spectroscopic methods (FT IR, FAB Mass,1H NMR and UV). An IR spectrum indicates that the ligand behaves as bidentate ligands. The

Formation of water soluble deeply colored ternary complexes of metal ions show large bathochromic shift. Same stoichiometric composition of ternary complexes with 1:2:4 molar ratio (M-CRAS-CDMEAB) have been observed for both the metal ions and are responsible for enhancement in molar absorptivities and sensitivities at shifted wavelength.

The iconography of the image follows the generally accepted models of the time and the theme reflects the average practice of festivities, occurring in the daily life of Byzantine society. The context of the artifact and the related findings suggest the bowl as one of the constituent elements of the thematically united table ware set, representing the main features of the elite banquet and

E and the IV th International Heparin Standard were both used as internal standards.The anti IIa and CTT effects were only measurable when the injected dose was higher than 40 mg. The maximum anti-Xa and anti-IIa ACT were obtained 3 to 4 hours after the dose. As anti-IIa ACT is lower tha
