Robinson Faculty of Science Department of Chemistry University of Malaya 50603 Kuala Lumpur, Malaysia E-mail: nura_suleiman@yahoo.com New Schiff-bases ligands of hydrazones derivatives 3, 4, 5-trihydroxy-N-(1-(2-hydroxy-5-methoxy phenyl)ethylidene)benzohydrazide, 3, 4, 5-trihydroxybenzoic acid [1-(pyridyl)-ethylidene]hydrazide, 3,4,5-trihydroxy-benzoic acid[1-(4-acetyl-ptridin-2-yl)-ethylidene]-hydrazide, (E)-N-(1-(5-bromo/chloro2-hydroxyphenyl) ethylidene) -3,4,5-trihydroxy benzohydrazide and (E)-N- (1-(chloro-2-hydroxyphenyl) ethylidene)-3,4,5- trihydroxy benzohydrazide and their respective complexes of Cd(II), Ni(II), Cu(II) and Zn(II) were synthesized and characterized. The ligands are derived from the condensation reaction of gallic hydrazide (derived from reactions of 3, 4, 5–trihydroxy benzoate and hydrazine hydroxide as the starting material) with acetophenone derivatives and pyridyl ketones. Both the Schiff -base ligands and their respective complexes have been characterized by elemental analysis of vari ous spectroscopic 1 methods (FT-IR, H-NMR, UV-Visible) and X-Ray diffraction method was used to confirm their structures. 132 3rd ICYC 2010 Universiti Sains Malaysia INO-P2 23rd-25th June 2010 PREPARATION AND SPECTRAL CHARACTERISTICS OF DIORGANOTIN(IV) COMPLEXES OF N -PHENYL-MMETHOXYBENZOHYDROXAMIC ACID 1,2 Abdualbasit Graisa, 1,3 Yang Farina, Emad Yousif and Elhadi E Saad 3 4 1 School of Chemical Science & Food Technology, University Kebangsaan Malaysia, Malaysia 2 Higher Institute of Medical Technology, Misurata, Libya 3 Department of Chemistry, College of Science, Al-Nahrain University, Baghdad, Iraq 4 Department of Chemistry, Faculty of Science, University of Sebha, Libya E-mail: graisa61@yahoo.co.uk New diorganotin(IV) complexes of the type Ph2SnL2, Bu2SnL2 and Me2SnL2 of the ligand N-phenyl-mmethoxybenzohydroxamic acid. Ligand formed by condensation reaction of 3-methoxybenzoyl chloride with N- phenyl hydroxylamine in presence of sodium hydrogen carbonate as a catalyst. The prepared complexes were characterized by elemental analysis...
