  Cd(ΙΙ) and Mn(ΙΙ) complexes of a new hexadentate Schiff base ligand derived from an asymmetric tripodal tetraamine and 2-pyridinecarboxaldehyde

  摘要：

  Two new compounds, [CdL22pyfp(NO(3)AClO(4)) (1) and (MnL22pyfpCl](ClO4) (2), were prepared by the template condensation of a previously known ligand, (L-22py), and 2-pyridinecarboxaldehyde in the presence of Cd(NO3)(2)center dot 4H(2)O or MnCl2 center dot 4H(2)O in equimolar ratios. The resulting compounds were characterized by elemental analysis, IR and single crystal X-ray diffraction, and by NMR in the case of the Cd(II) complex. The Cd(II) ion is in an eight-coordinate environment that is best described as a distorted dodecahedron. The environment around the Mn(II) ion may be described as a distorted pentagonal bipyramid. The H-1 NMR spectrum of the cadmium complex shows the signal of the imine proton to have two satellites ((3)J = 44.4 Hz) with intensities of 1:61 due to coupling with the neighboring Cd-111/113 atom. The electronic spectra of both complexes, as well as the ligand, is explained on the basis of TD-DFT calculations. (C) 2008 Elsevier Ltd. All rights reserved.
