Pompon-Like MnF2 Nanostructures from a Single-Source Precursor through Atmospheric Pressure Chemical Vapor Deposition

MnF2 nanorod assemblies in a pompon-like fashion were synthesized by using a new complex, Mn(hfa)(2) center dot tmeda [(Hhfa = 1,1,1,5,5,5-hexafluoro-2,4-pentandione, tmeda = N,N,N',N'-tetramethylethylenediamine)]. The complex was synthesized in a single-step reaction, and single-crystal X-ray diffraction studies provide evidence of a mononuclear structure. The thermal analyses have shown that the complex is thermally stable and can be evaporated to leave less than 2% residue at atmospheric pressure. On the basis of its thermal properties, it has been successfully applied to the atmospheric pressure metalorganic chemical vapor deposition (AP-MOCVD) of MnF2 nanostructures.
