dc.description.abstractSchiff base chemistry was elaborately studied using the anionic ligands obtained by reacting, various primary aryl amines with medicinally important salicyldehyde. Different ligands, ranging from simple non rigid bidentate/tridentate anionic Schiff base ligands to sterically free twisting ligands have been prepared. All these ligands were complexed with transition metals like cobalt, nickel, copper and zinc. The coordination complexes of square planar and distorted tetrahedral geometry were obtained for bidentate anionic Schiff base ligands and octahedral for tridentate Schiff base ligands. Characterization of all the Schiff base ligands were done using various spectroscopic and analytical methods including 1H, 13C{1H}-NMR, infrared spectroscopic method, ES+-MS, elemental analyses and conductance studies. Apart from it Schiff base ligands like 2-[(E)-(quinolin-3-ylimino)methyl]phenol (H-QMP), [1-({[(Z)-(2-hydroxynaphthalen-1-yl)methylidene]amino}methyl)cyclohexyl]acetic acid (H-HHMAC) and 2-(2-hydroxyphenyl)-3-{[(E)-(2-hydroxyphenyl)methylidene]amino}-2,3-dihydroquinazolin-4(1H)-one (H-HHAQ) were recrystallized from concentrated THF solution in Pc, P1 and C2221 space groups respectively. All the synthesized transition metal complexes of the representative Schiff base ligands were also characterized by elemental analyses, ES+-MS, IR and UV Visible spectroscopic studies, magnetic susceptibilities and molar conductance studies. The metal complexes like 1 and 2 were recrystallized by slow diffusion of diethyl ether into the concentrated solution of metal complexes in CH2Cl2 in P21/c space group having trans square planar arrangement of ligand around the metal centers.
