Title A name given to the resource Synthesis and characterization of acid hydrazone complexes Creator An entity primarily responsible for making the resource Anil Juje Fernandes Date A point or period of time associated with an event in the lifecycle of the resource 2012 Source A related resource from which the described resource is derived Chemistry Description An account of the resource The new azomethine compounds derived from Acetophenone benzhydrazone and Acetophenone nicotinicacidhydrazone have been prepared Further it is synthesized with Cu(II) and Co(II) salts to form stable complexes. The ligand and metal complexes have been characterized by Elemental analysis, IR, NMR, UV/Vis Spectrometry, Vibrating sample magnetometric measurements and Gouy Balance method. The nature of bonding and the stereochemistry of the complexes have been deduced from infrared spectra, electronic spectra, magnetic susceptibility, and an octahedral geometry has been suggested for cobalt (II) and square pyramidal structure for copper (II) complex. The complexes are non-hygroscopic, and photo stable crystalline powders with different melting point. The solubility of the metal-complexes in various solvents confirmed the diversity of the complexes as the ligands. The coordination process takes place through the carbonyl oxygen and the azomethine nitrogen atom, the anionic ion is in the outer sphere of the copper complex. The complexes were proposed to have the formulae [ML1.phen(H2O)]NO3H2O. where M=Cu(II),Co(II) ,and HL1 = acetophenone benzhydrazone and [MHL2phen.( NO3)2 ]H2O HL2 = Nicotinic acid acid hydrazone KEY WORDS: Complexes, Hydrazones, Acetophenone, Synthesis, Characterization.
