  LIGATIONAL BEHAVIOR OF FURFURYLIDENE(N-BENZOYL)GLYCYL HYDRAZONE TOWARD SOME TRANSITION METAL IONS

  摘要：

  Furfurylidene(N-benzoyl)glycyl hydrazone, FBzGH, has been synthesized and characterized. Transition metal complexes of the formulae [M(FBzGH)(2)Cl(H2O)]Cl (M = Mn, Cu, Zn, Cd, Hg), [Co(FBzGH)(2)]Cl-2.H2O and [Ni(FBzGH)(2)Cl-2].H2O were isolated from acidic solutions and the complexes [M(FBzG)(2)(H2O)(2)] (M = CO, Ni, Cu), from neutral solutions. Elemental analyses, molar conductances, magnetic susceptibilities, electronic, pH-metric, ESR, IR, and NMR studies have been carried out on these complexes to illuminate the ligational behavior of FBzGH toward the divalent metal ions. Formation constants of the metal chelates were determined pH-metrically in aqueous dioxane. IR and NMR spectra suggest a bidentate nature of the hydrazone coordinating as a neutral species in the adducts and as a uninegative one in the neutral complexes. H-1 NMR spectra indicate the presence of two different conformers of the ligand at room temperature even after complexation. However, these spectra show coalescence of the peaks at a temperature higher than 340 K indicating that one of the conformers gets stabilized at a higher temperature. A highly shielded chemical shift value of(113). Cd NMR suggests a strongly bound but weakly coordinated Cd2+ ion.
