  摘要：

  AbstractTricarbonylrhenium(I) and ‐technetium(I) halide (halide = Cl and Br) complexes of ligands derived from 4,5‐diazafluoren‐9‐one (df) and 1,10‐phenanthroline‐5,6‐dione (phen) derivatives of benzoic and 2‐hydroxybenzoic acid hydrazides have been prepared. The complexes have been characterized by elemental analysis, MS, IR, 1H NMR and absorption and emission UV/Vis spectroscopic methods. The metal centres (ReI and TcI) are coordinated through the nitrogen imine atoms and establish five‐membered chelate rings, whereas the hydrazone groups stand uncoordinated. The 1H NMR spectra suggest the same behaviour in solution on the basis of only marginal variations in the chemical shifts of the hydrazine protons.

  This paper shows the characteristics of a coordinated compound formed by zinc(11) and di-2-pyridyl ketone salicyloylhydrazone (DPKSH). The synthesized complex shows the formula: Zn(DPKSH)(2). Elemental analysis, electron ionization and electrospray mass spectra indicated the 1:2 metal/ligand molar ratio. The IR spectra show that DPKSH is coordinated to zinc(II) through the oxygen from the enolic or the phenolic group as the nuCO frequency was suppressed and the nuCO (phenolic) band was shifted to higher frequency in the IR spectrum of the complex. Two other interactions can be attributed to the nitrogens from the azo and the pyridine groups. Thermal decomposition and differential scanning calorimetry (DSC) are different for the ligand and the complex. The overall formation constants were obtained in ethanolic solution 50% (V/V), at pH 4.5 and 25 degreesC, resulting in beta(1) = 1.07 x 10(5) and beta(2) = 1.05 x 10(10). The molar absorptivies of the 1: 1 (epsilon(1)) and 1:2 0;2) complexes (Zn(11):DPKSH) were found to be 1.1 x 10(4) and 4.5 x 10(4) (M(-1)cm(-1)), respectively. (C) 2004 Elsevier Ltd.
