【 摘 要 】

The coordination chemistry towards the M(II) metal centre (M = Mn, Ni, Cu or Zn) of the hydrazone ligand (E)-2-amino-N’-[1-(pyridin-2-yl)ethylidene]benzohydrazide (H3L) has been explored and complexes having formulae [Mn(H2L)2] (1), {[Ni(H2L)2].DMF.0.4H2O} (2), {[Cu2(H2L)2(µ-Cl)2].DMF} (3) and [Zn(H2L)2] (4) have been isolated and characterized by IR, UV-Visible spectroscopy, elemental analysis and X-ray crystal diffraction. Structural studies reveal that the mononuclear complexes (1), (2) and (4) adopt highly distorted octahedral geometries while the dinuclear complex (3) adopts a square pyramidal geometry around each copper(II) ion.
