First Transition Metal Complexes Salts of Diazonium Derived from Nitrogen Heterocyclic Compound, Synthesis, Characterization and Biological Activity
...Show More Authors

Metal complexes chrome(III), manganese(II), iron(III), cobalt(II), nickel(II), cupper(II) and zinc(II) with diazonium of 3-amino-2-chloropyridine of general formula [2-Cl-C5H3N≡N]n[MXm], where n=2 or 3 for divalent and trivalent metal, m= 4 or 6  were synthesized. The complexes have been characterized by flame atomic absorption, (C.H.N), molar conductance, magnetic susceptibility UV-vis spectra, infrared spectra,1H-NMR spectroscopy and thermo gravimetric analysis (TGA and DTA). The measurements showed that the divalent metal ion complexes (M2+) have (1:2) M:L ratio with tetrahedral geometry around metal ions while the trivalent metal ions (M3+) formed (1:3) metal: ligand ratios with octahedral geometry. Furthermore, the complex salts were displayed for antibacterial activity versus two types of bacteria Gram, positive (Staphylococcus aureus) and Gram negative (Klebsiella pneumonia). The complex 2 Mn(II) and 3 Fe(III), exhibited moderate activity against the two tested bacteria, while the complexes  1 Cr(III), 4 Co(II) 6 Cu(II) and 7 Zn(II) showed high activity .The complex 5 Ni(II) displayed moderate and weak against the type one and type two of bacteria respectively.

Since the word of the Quran that put an end to all words which kneeled before it all the phrases that lead to the showcasing of the Arabic language in its best self.
Arab scientist realized this truth and gave all their attention to the singular and created from it an important subject for their research in the origins of the language and the science behind. Thus, since they dealt with the structure and studied the significance of the context through the use of vocabulary. Therefore, researching Islamic words or the “surat” mentioned in the Qur’an was necessar
