Abstract:The ligand (LH) [P-hydroxy phenyl benzilidene] derived from a condensation product of p-hydroxy aniline and benzaldehyde and its complexes with Cobalt(II), Nickel(II) and Copper(II) has been synthesized and characterized by metal analysis molar conductance, magnetic moments, Infrared Spectra. The complexes were observed to Preparation and Study of Some New Schiff Base Complexes of Co(II), Ni(II) ... 2have an octahedral geometry around central metal ion in both neutral and basic media. The stoichiometry reaction between the metal (II) ion and synthesized ligand in molar ration of M: L (1:1) in both neutral and basic media. In neutral media forms the metal complexes of type of [M 2 (LH) 2 (H 2 O) ٤ Cl ٤ ] while in basic media forms type [M 2 (L) 2 (H 2 O) 6 Cl 2 ] (where M= Co(II), Ni(II), or Cu(II), LH=C 13 H 11 NO, L= C 13 H 10 NO) respectively. The infrared spectra of free ligand and all complexes reveal that the ligand has been coordinated to metal ion through the nitrogen of azomethine group and oxygen atom of phenol group in neutral media but in alkaline medium acts as mono basic. In all these complexes the metal ions are hexacoordinate with most probable octahedral structure. Introduction:Schiff bases are considered as a very important class of organic compounds, which have wide applications in many biological aspects [1]. Transition metal complexes of Schiff base are one of the most adaptable and thoroughly studied systems. These complexes have also application in clinical, analytical and industrial in addition to their important roles in catalysis and organic synthesis [2]. Studies of a new kind of chemotherapeutic Schiff bases are now attracting t...
