Pure and Pt-doped ZnO nanophase particles were synthesized using the ultrasonic spray pyrolysis. Particles were obtained through decomposition of zinc nitrate and new developed Pt(IV) complex with 1,3-propylenediamine-N,N-diacetate ligand (pdda) belonging to the tetradentate class. The complex is characterized by elemental analysis, electronic absorption and infrared spectra. The crystal structure of trans-[Pt(pdda)Br_2]·H_2O complex has been determined implying that Pt(IV) ion has a distorted octahedral coordination due to intramolecular N-H ...Br interaction. Ultrasonically derived pure and Pt-doped ZnO particles were characterized by XRD, SEM, EDS and TEM analysis. It was shown that zincite phase exhibits different growing morphologies influenced by precursor chemistry and processing parameters. The composite inner structure, primary particle size and mechanism of Pt 4+ ion introducing into ZnO cell is discussed based on structural refinement and selected area electron diffraction analysis.
