    <subfield code="a">N-(2-1{[(2E)-2-(2-hydroxybenzylidene)hydrazinyl]carbonyl}phenyli)benzamide (HL) and its Co(II), Fe(III), Cu(II) and Zn(II) perchlorate complexes were synthesized. The structures of HL and its complexes were confirmed on the basis of elemental analysis and FT-IR, FT-Raman, H-1-NMR spectra. TGA, magnetic moment and molar conductivity measurements were carried out for the complexes. In addition, the crystal structure of HL was determined by X-ray diffraction at room temperature. It crystallizes in the monoclinic, space group C2/c and Z=4. HL has an interesting structure due to the presence of two intramolecular hydrogen bonds. It behaves as a bidentate ligand through the C=N nitrogen and OH oxygen atoms in its chelate complexes that they have 1:2 M:L (metal:ligand) ratio. The Fe(III), Cu(II) and Zn(II) complexes, [Fe(HL)(L)(H2O)(2)](ClO4)(2), [Cu(HL)(2)](ClO4)(2 center dot)3H(2)O, [Zn(HL)(2)](ClO4)(2)center dot H2O are 2:1 electrolytes whereas the Co(II) complex, [Co(HL)(L)(H2O)]ClO4 center dot H2O, is 1:1 electrolyte according to the molar conductivity data.</subfield>
