The molecules are linked by N-H…O hydrogen bonds forming a supramolecular chain structure. On the hand, a dimeric octahedral oxovanad ium(V) complex was formed from the direct reaction of vanadyl acetylacetonate with substituted benzoic acid hydrazide. 138 3rd ICYC 2010 Universiti Sains Malaysia INO-P13 23rd-25th June 2010 SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF MULTIDENTATE AZOMETHINE SERIES AND THEIR Cu(II) AND Ni(II) COMPLEXES DERIVED FROM GUANIDINE N Nurdini, B Hadariah, K Karimah and MZ Mazatulikhma Department of Chemistry, Faculty of Applied Sciences, Universiti Teknologi MARA 40450 Shah Alam, Selangor, Malaysia E-mail: [email protected] A series of azomethine compounds of guanidine compound as ligands H 2L1:C15H13N3O4 and H2L2:C17H17N3O4 were synthesized from 2,4-dihydroxybenzaldehyde and 2’,4’-dihydroxyacetophenone. The metals selected for the preparation of complexes were Cu( II) and Ni(II) namely CuL1, CuL2, NiL1 and NiL2. All the synthesized compounds were characterized by Fourier Transformed Infrared (FTIR), CHN 1 elemental analysis, Proton Nuclear Magnetic Resonance ( H NMR), X- Ray crystallography and Magnetic susceptibility measurements. The shifted of all complexes was compared to the ѵ(C=N) bands of ligand -2 -2 H2L1 at 1639.84 cm and H2L2 at 1632.50 cm . The magnetic properties shown that copper(II) complexes were diamagnetic while nickel(II) complexes were paramagnetic and non-electrolytic in solution. An investigation for cytotoxicity assay was tested by using cancer cell namely neuroblastoma cells. The obtained results were compared to the normal cells and also the results reported by Brzozowski et al., (2007).
