Synthesis of new nano schiff base complexes: X-Ray crystallography, thermal, electrochemical and anticancer studies of nano uranyl schiff base complexes

This study presents synthesis and characterization of new nano uranyl Schiff base complexes. Electrochemistry of these complexes showed a quasireversible redox reaction without any successive reactions. Furthermore, X-ray crystallography exhibited that beside the coordination of tetradentate Schiff base, one solvent molecule (dimethylformamide) was also coordinated. According to Coats-Redfern plots the kinetics of thermal decomposition of the studied complexes was first-order in all stages. Anticancer activities of the uranyl Schiff base complexes against cancer cell lines (Jurkat) was studied and determined by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazoliumbromide) assay. The results demonstrated that the complexes with aliphatic bridging units showed less anticancer activities than those having the aromatic units.

Synthesis, reactivity, thermal, electrochemical and magnetic studies on iron(III) complexes of tetradentate Schiff base ligands

Cationic iron(III) complexes of the type [FeLn(H 2O)2]NO3 (n = 1 or 2) were accessed from the interaction of Fe(NO3)3·9H2O with [N2O2] donor Schiff base (L) in 1:1 molar ratio. The Schiff base ligands were prepared from condensation of 2-hydroxy-1- naphthaldehyde with o-phenylenediamine or ethylenediamine in 2:1 molar ratio. Reaction of the aquated complexes with neutral N-donor molecules (X) viz. imidazole, benzimidazole and pyridine led to substitution of weakly held axial aquo groups affording new mixed ligand complexes, [FeLnX 2]NO3. The compounds were characterized by elemental analyses, FT-IR, UV-Vis, solution electrical conductivity, FAB mass, 1H and 13C NMR (ligands only) spectroscopy. The thermal study provided unambiguous evidence for the occurrence of coordinated water in the complexes. Room temperature magnetic susceptibility measurements are consistent with high spin octahedral iron(III) complexes. Cyclic voltammetry revealed a quasi-reversible one electron redox response (ΔEp > 100 mV) assignable to Fe(III)/Fe(II) couple with negative half wave potential. The ground state geometries of the aquo complex, [FeL 2(H2O)2]NO3 and pyridine complex, [FeL2(Py)2]NO3 were ascertained by density functional theory using dmol3 program with BLYP functional.

New sodium dodecyl sulfate-assisted preparation of Nd2O3 nanostructures via a simple route

The effect of the anionic shape- and size-controller on the morphology and size of Nd2O3 prepared by a new simple approach was studied. Nanostructured Nd2O3 was synthesized by heat treatment in air at 900 °C for 5 h, employing powder, which was prepared by a solvent-free solid-state reaction from [NdL(NO3)2]NO3 (L = bis-(2-hydroxy-1-naphthaldehyde)-ethanediamine Schiff base compound), as a new precursor, in the presence of sodium dodecyl sulfate (SDS) as shape- and size-controller. The structural, morphological and optical properties of the as-obtained nanostructured Nd2O3 were characterized by thermo-gravimetric analysis (TGA), X-ray diffraction (XRD), energy dispersive X-ray microanalysis (EDX), UV-vis diffuse reflectance spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) spectroscopy. The obtained results demonstrated that the amount of SDS plays a key role in the morphology and particle size control of the neodymium oxide. Furthermore, the catalytic properties of the as-prepared nanostructures were evaluated by the photocatalytic degradation of the erythrosine (anionic dye) as water contaminant.

Evaluation of photochemotherapeutic potential of a few oxo-bridged dimeric Fe(III) compounds having Salen-type ligands

Four oxo-bridged dimeric Fe(III) complexes, viz. [(μ-O){Fe(L)}2] (1–4), where L is N,N?-bis(naphtalidene)-ethylenediamine, (H2L1 in 1); N,N?-bis(naphtalidene)-1,2-phenylenediamine, (H2L2 in 2); N,N?-bis(naphtalidene)-4-nitro-1,2-phenylenediamine (H2L3 in 3) and N,N?-bis(naphtalidene)-4-carboxyl-1,2-phenylenediamine, (H2L4 in 4) were synthesized for their potential application as photochemotherapeutic agents in low energy visible light. The solid-state structure of complex 2 was confirmed by X-ray crystallography. The complexes bind to human serum albumin (HSA) reversibly in a pH dependent manner, which could be a potential carrier of the molecules in blood plasma. They also bind to calf-thymus (ct) DNA with considerable affinity. In vitro cellular experiments show that the complexes display significant photo-enhanced cytotoxicity in human cervical cancer (HeLa) and human breast cancer (MCF-7 and MDA-MB-231) cells with low dark toxicity. ICP-MS analysis show that the complexes enter HeLa cells in a dose-dependent manner. Flow cytometric and confocal microscopic experiments demonstrate that the complexes kill cancer cells on exposure to visible light primarily via apoptosis through the generation of reactive oxygen species (ROS).

Temperature and frequency dependent dielectric properties of electrically conducting oxidatively synthesized polyazomethines and their structural, optical, and thermal characterizations
