    Abstract: This paper begins with a detailed description of the conditions necessary for the formation of chelates in general, and ß-ketosulfoxides in particular. While symmetric chelates such as 2,4-pentanedione have been known and studied for a long time, asymmetric chelate structures, such as the aliphatic ω-(methylsulfinyl)-acetophenone, Ph-CO-CH2-SO-CH3,...

    Abstract: Schiff base ligands were synthesis via a condensation of the ligands in methanol in 1:1:1 molar ratio reactions. The transition metal(II) complexes were formed by the reaction of Co, Cu, Mn, Fe with the Schiff base and ampicillin and they were characterized via FTIR, electronic spectra, melting points, solubility and molar conductance. The invitro ... Show More

    Abstract: The Schiff base 1-(benzothiazol-2-yl)(2-pyridylmethylidene)hydrazine (HL) was synthesis via a condensation of 1-(benzo[d]thiazol-2-yl)hydrazine and 2-pyridine carboxaldehyde in methanol in 1:1 molar ratio reaction. The crystal structure of a mononuclear complex Bis[1-(benzothiazole-2yl-2κN)(2-pyridylmethyliden-1κN)(hydrazino-2κN)] cobalt(II) comple... Show More
