A novel Schiff base ligand (L) was prepared through condensation of 2,6-diaminopyridine and dibenzoyl methane in a 1:1 ratio. This Schiff base ligand was used for complex formation reaction with Fe(III) chloride. The structures of the ligand and its complex were deduced from elemental analyses, mass spectroscopy, 1H NMR, IR, UV-visible, electronic spectra, magnetic moment, molar conductivity measurements, thermogravimetric analyses and x-ray diffraction. The mol. and electronic structures of both ligand and complex were optimized theor. using d. function theory (DFT) method. Moreover, the antimicrobial activities of the prepared compounds were studied and proven against some pathogenic bacteria. The Fe(III) complex had higher biol. activity than that of the free ligand. Proceeding from the collected information, the properties of the complex were further studied. The particle size was determined by dynamic light scattering technique to be 92.59 nm. Textural properties of the nano complex were studied by N2 adsorption to estimate the sp. surface area, pore volume and pore size distribution. The pores in the complex were found in the micropore-mesopore range. Differential scanning calorimetric measurements reveal the existence of four endothermic peaks at 243.8, 308, 339.8 and 380.5 K. Dielec. properties and conductivity were scanned at different frequencies and temperatures The dielec. constant reaches a peak value of 600 at ∼390 K, 30 Hz. A cross-over from the universal dielec. response to the super linear power law of conductivity is reported for this complex at T ≤ 345 K. Finally, the AC-magnetic susceptibility measurements were carried out in the low-temperature region. The complex showed paramagnetic behavior with a slight change in the magnitude of its magnetic moment at T = 244 K. In the experimental materials used by the author, we found 2,6-Diaminopyridine(cas: 141-86-6Recommanded Product: 141-86-6)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Recommanded Product: 141-86-6
