Synthesis and characterization of Co(II), Ni(II), Cu(II) complexes of schiff base obtained from 1,8-diaminonapthalene

ABSTRACT Master Thesis SYNTHESIS AND CHARACTERIZATION of Co(II), Ni(II), Cu(II) COMPLEXES of SCHIFF BASE OBTAINED FROM 1,8-DI AMINON APHTH ALENE Nevin TURAN Fırat University Graduate School of Natural and Applied Sciences Department of Chemistry 2003; Page: 34 In this work, 8-amino-[l-(2-hydroxyphenyl)imino]naphthalene (LH) and its some transition metal complexes were synthesized. 8-amino-[l-(2-hydroxyphenyl)imino]naphthalene (LH) has been prepared via the condensation of 1,8-Diaminonaphthalene and salicylaldehyde. Then, Co(II), Ni(II) and Cu(II) complexes were synthesized by this ligand. The structure of synthesized ligand and complexes were characterized by using Molar conductance, Elemental Analysis, Magnetic Susceptibility, IR, UV-VIS, 'H-NMR Spectroscopy techniques. It is concluded that Co(II), Ni(II) and Cu(II) complexes have square -planer geometry, tetrahedral geometry and square-planer (dimerik) structure, respectively. Key Words: 1,8-Diaminonaphthalene, Salicylaldehyde, Schiff Base and Co(II), Ni(II), Cu(II) complexes. Ill
