  Iodide Complexes of Yttrium and Lanthanides with 4-N-(4′-Antipyrylmethylidene)aminoantipyrine

  摘要：

  Yttrium and lanthanide iodide complexes with the Schiff base 4-N-(4'-antipyrylmethylidene)aminoantipyrine (AA) of the composition [Ln(AA)(2)I]I-2 (where Ln = Y, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho and Er) have been synthesized and characterized by elemental analyses, electrical conductance in non-aqueous solvents, magnetic susceptibility measurements, IR, electronic (in the solid and liquid states) as well as proton NMR (M = La and Y) spectra and thermogravimetric analyses. The Schiff base AA acts as a neutral tridentate ligand in all these complexes, coordinating through the oxygens of both carbonyl groups and the azomethine nitrogen. Only one of the iodide ions is coordinated to the metal ion. A coordination number of seven may be assigned to the metal ion in these complexes.

  In the perchlorate complex, one of the perchlorate ions is coordinated bidentately while in the nitrate complex two of the nitrate ions are coordinated monodentately to the metal ion. In the thiocyanate and chloride complexes all the anions are coordinated while in the bromide complex two of the bromide ions are coordinated. A high spin octahedral geometry is assigned to the iron(III) ion in all these

  Copper(II) complexes of the Schiff bases 1,2-di(imino-4 ' -antipyrinyl)ethane (GA) and 4-N-(4 ' -antipyrylmethylidene)amino-antipyrine (AA) have been synthesized and characterized by elemental analyses, electrical conductance in non-aqueous solvents, infrared, electronic and EPR spectra as well as magnetic susceptibility measurements. The complexes have the general formulae [Cu(GA)]X-2 (where X = ClO4 or NO3), [Cu(GA)X-2] (where X = Cl or Br), [Cu(AA)(2)]X-2 (where X = ClO4, NO3 or Cl) and [Cu(AA)Br]Br. GA acts as a neutral tetradentate ligand coordinating through both carbonyl oxygens and both azomethine nitrogens. In the perchlorate and nitrate complexes of GA, both anions remain ionic while in the corresponding halide complexes both anions are coordinated to the metal ion. AA acts as a neutral bidentate ligand coordinating through one of the carbonyl oxygens and the azomethine nitrogen in the perchlorate, nitrate and chloride complexes, while the coordination of AA occurs in a neutral tridentate fashion through both carbonyl oxygens and the azomethine nitrogen in the bromide complex. In the perchlorate, nitrate and chloride complexes of AA both anions remain ionic, while in the bromide complex, one of the bromides is coordinated to the metal ion. A square-planar geometry is assigned around the Cu(II) ion in all these complexes except the chloride and bromide complexes of GA, which are of distorted-octahedral geometry.
