Abstract
Abstract The preparations of 1,1,1,2,2,3,3,7,7,8,8,9,9,9-tetradecafluorononane-4,6-dione (tdfH) and the Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), and Pd(II) metal complexes of its monoanion (tdf) are described. The metal complexes have been characterized by elemental analysis, IR and visible spectroscopies, magnetic moment for the paramagnetic compounds, and 1H and 19F NMR spectroscopy for the Zn(II) and Pd(II) complexes. X-ray structural studies of Cu(tdf)2 · C2H5OH, Cu(tdf)2 · 2H2O, and Mn(tdf)2 · 2H2O were undertaken. The geometry of the Cu(II) ethanolate complex is square pyramidal, while the Cu(II) dihydrate complex is distorted octahedral with the two aquo ligands occupying trans coordination sites. The Mn(II) dihydrate complex appears also to have distorted octahedral geometry with the two aquo ligands situated cis to each other.
