Nanorods of a three-dimensional Zn(II) metal-organic framework, [Zn 2 (btec)(DMF) 2 ] n (1) (btec = 1,2, 4,5-benzenetetracarboxylate, DMF = N,N-dimethylformamide), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FE-SEM), powder XRD and FT-IR spectroscopy. Structural determination of compound 1 was determined by single crystal X-ray diffraction. The thermal stability of compound 1 has been studied by thermal gravimetric analysis

ZnO nano-structures also were simply synthesized by direct calcination of the single crystals and nano-sized compound 1 at 600°C. The size and morphology of the ZnO nano-structures are dependent upon the particles size of compound 1. A decrease in the particles size of compound 1 leads to a decrease in the particles size of the ZnO.
