Activation of the carbon dioxide molecule was achieved using bicyclic amidines (DBU, PMDBD, and DBN). The solution reaction CO(2) with yielded corresponding zwitterionic complexes through formation a N-CO(2) bond. (13)C NMR data confirmed carbamic nature zwitterions, DBU-CO(2) PMDBD-CO(2). However, when these adducts were crystallized, X-ray analyses single crystals in agreement bisamidinium bicarbonate salt structures, indicating that structural changes occurred crystallization process....
An intensive effort has been directed toward finding alternative drugs for treatment of Chagas' disease, caused by Trypanosoma cruzi, and prophylaxis blood in endemic areas. Our research comprises the synthesis trypanocidal screening derivatives from naphthoquinones. Herein a new phenazine, obtained reaction β-lapachone with aniline, its structure established physical data X-ray analysis. It was 9 times more active against T. cruzi trypomastigotes than crystal violet.
The complex trans-[Ru(NH3)4NO(H2O)]Cl3·H2O has been isolated as a decomposition product of the dimeric cation [{Ru(NH3)4NO}2(μ-S2)]6+. elemental analysis and electronic, infrared, X-ray, ESR spectroscopies fit well with formulation trans-[Ru(NH3)4NO(H2O)]Cl3·H2O. νNO (1912 cm- 1) observed ∠(Ru−N−O) = 178.1°(5) are consistent nitrosonium character NO ligand. Cyclic voltammetry showed only one redox process in range −0.5 to +1.2 V, which was attributed reaction trans-[(H2O)(NH3)4RuII(NO+)]3+ +...
The effect of addition different amounts acetylacetone (acacH) on the species formed at room temperature and after thermohydrolysis 70 °C for 30 120 min ethanolic SnCl4·5H2O solutions is followed by EXAFS spectroscopy Sn K-edge. We show that thermohydrolyzed are a mixture SnO2 nanoparticles soluble tin polynuclear species. complexation molecular precursors acetylacetonate ligands evidenced 1H, 13C, 119Sn NMR acacH/Sn ratio higher than 2. Single crystals isolated from solution structure,...
Abstract Julocrotine, N ‐(2,6‐dioxo‐1‐phenethyl‐piperidin‐3‐yl)‐2‐methyl‐butyramide, is a potent antiproliferative agent against the promastigote and amastigote forms of Leishmania amazonensis ( L. ). In this work, crystal structure Julocrotine was solved by X‐ray diffraction, its geometrical parameters were compared with theoretical calculations at B3LYP HF level theory. IR NMR spectra also have been obtained calculations. absorptions calculated theory employed together 6‐311G+(d,p) basis...
Abstract The synthesis, structural characterisation and magnetic properties of a new chloro‐bridged linear chain imine‐copper(II) compound are reported. results indicate that uniform chains formed by stacking parallel pyramidal units from the copper centre coordinated to imine ligands bridged chloride ions, with uncoordinated perchlorate ions located between layers balance charge. Magnetic measurements carried out on powder sample at temperatures 1.8 290 K field 500 Oe, indicated an...
