We present the results of a spectroscopic analysis extremely strong damped Lyman-{\alpha} absorbers (ESDLAs, log N(Hi)>=21.7) observed with VLT-XShooter. ESDLAs probe gas from within star-forming disk associated galaxies and thus provide unique opportunity to study interstellar medium at high-redshift. report column densities (N), equivalent widths (w), kinematic spread ({\Delta} v90) species n...

In a previous paper some of us presented the structure and properties new family ionic liquids, ILs, with common cation, 1-butyl-3-methyl imidazolium (the popular [C4C1Im]+ or [BMIM]+) variety anions based in thiocyanate (SCN)−: one reference sample ten anionic metal complexes different valences: AlIII, MnII, FeIII, CrIII, NiII, HgII, ZnII, CoII CuI, resulting, respectively, [BMIM](SCN), [BMIM]...

A new thiosemicarbazone (LH2) derived from indole-7-carbaldehyde was synthesized and reacted with Zn(II), Cd(II), Pd(II) and Pt(II) salts. The reactions with zinc and cadmium salts in 2 : 1 (ligand-metal) molar ratio afforded complexes of the type MX2(LH2)2, (X = Cl, Br or OAc), in which the thiosemicarbazone acts as a neutral S-monodentate ligand. In the presence of potassium hydroxide, the re...

BACKGROUND Complexes of imidazole derivatives with transition metal ions have attracted much attention because of their biological and pharmacological activities, such as antimicrobial, antifungal, antiallergic, antitumoural and antimetastatic properties. In addition, imidazoles occupy an important place owing to their meaningful catalytic activity in several processes, such as in hydroaminatio...

Three new oxoaporphine Co(II), Ni(II) and Zn(II) complexes 1-3 have been synthesized and fully characterized. 1-3 have similar mononuclear structures with the metal and ligand ratio of 1:2. 1-3 exhibited higher cytotoxicity than the OD ligand and cisplatin against HepG2, T-24, BEL-7404, MGC80-3 and SK-OV-3/DDP cells, with IC50 value of 0.23-4.31 μM. Interestingly, 0.5 μM 1-3 significantly cause...
