متن کاملSynthesis, Characterization and Biological Activity of Schiff Base Metal Complexes
New coordination complexes of Co, Ni and Zn with Schiff base N’-((2-thioxo-1,2-dihydroquinoline-3yl)methylene) pyridine-4-carbohydrazide have been synthesized and characterized by several techniques using elemental analysis (C, H, N), IR spectra and 1HNMR spectra. The new Schiff base has been synthesized by the reaction of pyridine-4-carbohydrazide and 2-thioxo-1,2dihydroquinoline-3-carbaldehyd...
متن کاملSynthesis and characterization of some transition metal complexes with new mixed-donor schiff base ligands derived from 2-hydroxynaphthaldehyde
2-[3-(2-Formylnaphthoxy)-2-hydroxypropoxy] naphthaldehyde (1) have been prepared by reaction of 2-hydroxynaphthaldehyde with 1,3-dichloro-2-propanol. New N2O3 macro-acyclic ligands (L1, L2) synthesized from the reaction of (1) with aniline or cyclohexylamine. Ni (II), Co (II) and Cu (II) complexes was prepared from reaction of Schiff-bases with metal chloride and nitrate salts. All of these com...
