Abstract

New Schiff base ligand 2-[-(4-bromobenzylidene) hydrazinylidene]-1,2-diphenylethanimine was synthesized via condensation of α-benzilmonoximehydrazone and 4-bromobenzaldehyde in ethanol. Complexes were obtained from 1:2 molar ratio reactions with metal ions and ligand, 2NA on reaction with MCl 2.nH2O salt yields complexes corresponding to the formulas [M(L)2 ],where M = Co(II), Ni(II) and Cu(II). The 1H-NMR, FT-IR, electronic absorption spectra and elemental analysis were used for the characterization of the ligand. The geometry of complexes elucidated by FT-IR, electronic absorption spectra, conductance, and magnetic susceptibility measurements. All complexes are non-electrolytes in nitrobenzene solution. Octahedral geometries have been suggested for each of the complexes. The ligand is bidentate and leads to deprotonation coordination.
