Synthesis, Characterization and Biological Studies of Some new Cr(III), Fe(III) and Cu(II) Complexes based on Multi-Substituted  Aryl Imidazole ligand
New Cr (III), Fe (III) and Cu (II) complexes with MSBB (2‐(1‐butyl‐4,5 diphenyl‐1H‐imidazol‐2‐yl)(4-bromophenol) were synthesized. The multi-substituted aryl imidazole ligand (MSBB) and its complexes were characterized by using elemental and thermal analysis, molar conductivity, magnetic susceptibility, UV-Vis spectral data, IR, and NMR. The obtained data showed that prepared complexes were 1 :1 (metal : ligand) ratio, octahedral (Oh) for all ... إقراء المزيد

Ni(II) and Cu(II) complexes : synthesis, spectroscopic characterization, theoretical calculations, DNA interaction and antimicrobial studies
A novel Schiff base, namely _Z_‐3‐((2‐((_E_)‐(2‐hydroxynaphthyl)methylene)amino)‐5‐nitrophenylimino)‐1,3‐dihydroindin‐2‐one, was synthesized from the condensation of 2‐hydroxy‐1‐naphthaldehyde and isatin with 4‐nitro‐_o_‐phenylenediamine. It was structurally characterized on the basis of 1H NMR, 13C NMR and infrared spectra and elemental analyses. In addition, Ni(II) and Cu(II) complexes of the Schiff base ligand were prepared. The nature of bonding and the stereochemistry of the investigated complexes were ... إقراء المزيد
