In this investigation, zirconia (ZrO2) nanopowders have been synthesized through the decomposition of a nano-structured zirconium(IV) coordination supramolecular compound, (pydaH)2[Zr(pydc)3]·5H2O (1), where [pyda.H]+ = 2,6-diaminopyridinium, and [pydc]2− = 2,6-pyridinedicarboxylate, as a new precursor. The compound 1 has been synthesized by sonochemical method and characterized by field emission scanning electron microscope (FESEM), X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and elemental analyses. The sizes of the nanostructures were approximately 50 nm. The thermal stability of compound 1 has been studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The XRD pattern of the residue obtained from thermal decomposition of compound 1 under argon and air atmospheres provided two different kinds of crystal systems of zirconia, tetragonal (t) and mixture of monoclinic (m) and tetragonal (t) with particles size about 35 and 28 nm, respectively. This study, demonstrates that the supramolecular compounds may be suitable precursors for the simple one-pot preparation of nano-scale metal oxide materials with different and interesting morphologies.
