Abstract

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.
