Schiff base has been prepared by the condensation of 2-naphthylamine (NA) with 5bromosalicylaldehyde (BSA). The ligand (NABSA) was isolated and characterized. Metal complexes have been synthesized by the interaction of NABSA with metal ions viz. Co(II), Ni (II), and Cu(II) in 1:2 molar ratio respectively. These complexes have been characterized by FT-IR, electronic spectroscopy, conductance mea...

Transition metal complexes offer great potential as diagnostic and therapeutic agents, and a growing number of biological applications have been explored. To be effective, these complexes must reach their intended target inside the cell. Here we review the cellular accumulation of metal complexes, including their uptake, localization, and efflux. Metal complexes are taken up inside cells throug...

in this work, we report results of calculations based on the density functional theory of different species metal-ozone, containing mercury, silver and gold. the chosen species range from small molecules and large transition-metal containing ozone with mercury, silver and gold complexes. a comparative analysis of the description of the metal-oxygen bond obtained by different methodologies is pr...

Coordination of the carbocyclic ring of hydroquinones to electrophilic transition-metal fragments such as Mn(CO)3+ and Rh(COD)+ produces stable pi-bonded eta6-complexes that are activated to facile reversible deprotonation of the -OH groups. The deprotonations are accompanied by electron transfer to the transition metal, which acts as an internal oxidizing agent or electron sink. With manganese...

Transition metal-alkane complexes-termed σ-complexes because the alkane donates electron density to the metal from a σ-symmetry carbon-hydrogen (C-H) orbital-are key intermediates in catalytic C-H activation processes, yet these complexes remain tantalizingly elusive to characterization in the solid state by single-crystal x-ray diffraction techniques. Here, we report an approach to the synthes...

a series of transition metal complexes with two thiosemicarbazide schiff bases, 1-(4-dimethylaminobenzyl- idene)thiosemicarbazide (abtsc) and 1-(2-pyridincarboxyl-idene) thiosemicarbazide (tcts) were synthesized with co(ii), ni(ii), zn(ii), cd(ii) and ag(i) salts (chloride and acetate). these complexes were characterized by different methods including proton nuclear magnetic resonance (1hnmr), ...
