摘要:
A new chelating ligand, ferrocenecarboxaldehyde 2,4-dichlorobenzoylhydrazone (HFdcbh), and seven metal complexes, M(Fdcbh)(2) [M=Co(II), Ni(II), Cu(II), Hg(II)] and Ln(HFdcbh)Cl-3. 4H(2)O(2) [Ln La(III), Sm(III) and Er(III)I, have been prepared and characterized by elemental analyses, IR and H-1 NMR spectra. The deprotonated HFdcbh ligand acts as a bidentate donor, coordinating to the metal ions via its nitrogen and oxygen atoms.
