Pompon-like MnF 2 nanostructures from a single-source precursor through atmospheric pressure chemical vapor deposition

MnF 2 nanorod assemblies in a pompon-like fashion were synthesized by using a new complex, Mn(hfa) 2·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 MnF 2 nanostructures. A mild approach, atmospheric pressure metalorganic chemical vapor deposition (AP-MOCVD), was applied for the fabrication of pompon-like assemblies of MnF 2 nanorods. Mn(hfa) 2·tmeda [(Hhfa = 1,1,1,5,5,5-hexafluoro-2,4- pentandione, tmeda = N,N,N?,N?-tetramethylethylenediamine)] was used as a single-source precursor
