Fabrication, Spectroscopic Characterization, Calf thymus DNA Binding Investigation, Antioxidant and Anti-cancer Activities of Some Antibiotic Azomethine Cu(II), Pd(II), Zn(II) and Cr(III) Complexes
This study was conducted to prepare novel azomethine chelates of Cu(II), Pd(II), Zn(II) and Cr(III) with tri-dentate dianionic azomethine OVAP ligand 2-[(2-Hydroxy-phenylimino)-methyl]-6-methoxy-phenol. The prepared compounds were characterized with the help of elemental analyses, spectral (NMR, FT-IR, UV-vis, mass), conductivity, magnetic and thermal measurements. The spectroscopic data suggest that the parent azomethine ligand bind to the investigated metal ions through both ... Read more

Design, Synthesis, Characterization and biological application of some new Schiff Base Cu(II), Pd(II) and Ag(I) Complexes
In this investigation, new Cu(II), Pd(II) and Ag(I) complexes with the tetra-dentate DSPH Schiff base ligand were synthesized. The DSPH Schiff base and its complexes were characterized by using different physicochemical and spectral analysis. The results revealed that the metal ions coordinated with DSPH ligand through azomethine nitrogen and phenolic oxygen. Cu(II), Pd(II) and Ag(I) complexes are present in a ... Read more

Synthesis, Characterization, Antimicrobial evaluation and DFT calculations of Fe(III), Ni(II) and Cu(II) complexes of tridentate ONO donor ligand
A series of Fe(III), Ni(II) and Cu(II) complexes of the type [Fe(L)(H2O)2Cl].2H2O, [Ni(L)(H2O)].2H2O and [Cu(L)(H2O)3].2H2O, where L bi-negatively tridentate Schiff base ligand derived from condensation between anthranilic acid and 2-hydroxy-benzaldhyde, have been synthesized. The proposed structures of the obtained complexes have been established from elemental analyses, UV-Vis., FT-IR, magnetic moment and conductivity measurements. Density Functional Theory (DFT) calculations were established ... Read more

The electric and thermoelectric properties of Cu(II)-Schiff base nano-complexes
have been widely investigated. However, their thermoelectric (TE) properties remain unreported. This work presents Cu(II)-Schiff base complexes as promising materials for TE power generation. Therefore, three Cu(II)-Schiff base complexes (namely, [Cu(C32H22N4O2)].3 2H2O, [Cu(C23H17N4O7Br)], and [Cu(C27H22N4O8)].H2O) have been synthesized in nanosized scale. The electric and TE properties have been studied and comprehensive discussions have been presented to promote the nano-complexes (NCs) ... Read more
