چکیده انگلیسی


• A novel nano-scale Zn(II) complex was synthesized by solvothermal method.
• Chemical structure of the nanostructures was characterized as well as bulk complex.
• The photoluminescence property of the complex was investigated at room temperature.
• The thermogravimetry and differential thermal analysis were carried out.
• Thermal decomposition of the nanostructures was prepared zinc oxide nanoparticles.

Nanoparticles of a novel Zn(II) Schiff base complex, [Zn(HL)NO3]2 (1), (H2L = 2-[(2-hydroxy-propylimino) methyl] phenol), was synthesized by using solvothermal method. Shape, morphology and chemical structure of the synthesized nanoparticles were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), Fourier Transform Infrared Spectoscopy (FT-IR) and UV–vis spectroscopy. Structural determination of compound 1 was determined by single-crystal X-ray diffraction. The results were revealed that the zinc complex is a centrosymmetric dimer in which deprotonated phenolates bridge the two five-coordinate metal atoms and link the two halves of the dimer. The thermal stability of compound 1 was analyzed by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The effect of the initial substrates concentration and reaction time on size and morphology of compound 1 nanostructure was investigated as well. Furthermore, the luminescent properties of the complex 1 were examined. ZnO nanoparticles with diameter between 15 and 20 nm were simply synthesized by solid-state transformation of compound 1 at 700 °C.
