摘要

Nanoparticles of a Zn(II) coordination polymer {[Zn(DADMBTZ)(CH3COO)(2)](n), DADMBTZ = 2,2%26apos;-diamino-5,5%26apos;-dimethyl-4,4%26apos;-bithiazole} were synthesized by reaction of Zn(NO3)(2)center dot 4H(2)O, CH3COONH4 and DADMBTZ by a sonochemical method. The nanoparticles were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy. [Zn(DADMBTZ)(CH3COO)(2)](n) was structurally characterized by single-crystal X-ray diffraction. In this four-coordinate compound with nearly C-2 symmetry, DADMBTZ is bidentate. The metal lies in a pseudo-tetrahedral environment and is ligated by the two bithiazole ring nitrogen atoms and an oxygen from each of the two monodentate acetates; 2-D networks are formed via N-H center dot center dot center dot O hydrogen bonds. Thermal stability of [Zn(DADMBTZ)(CH3COO)(2)](n) was studied by thermal gravimetric and differential thermal analyses. A ZnO nanostructure was obtained by direct thermolyses at 500 degrees C under air. The ZnO nanostructure was characterized by SEM, XRD, and FT-IR spectroscopy.
