Ni (II) and Mn (II) metal complexes of Schiff base derived from ethylenediamine, succinic acid and formaldehyde. The newly synthesized Schiff base complexes were characterized by elemental analysis, Melting point, conductivity, IR and UV-VIS spectral methods. The complexes have been tested using for the catalytic oxidation of benzylacohol using ecofriendly molecular oxygen as catalyst. The results show that Nickel complex shows highest yield oxidation product as compared to Manganese at 35°C temperature, 90mg catalyst amount and 25 min. time.

The Complexes of Co (II) and Ni (II) with amino acid cysteine were synthesized and characterized by FT-IR and spectrafluorometric Studies. The FT-IR spectra shows some new band which confirms that the complex is formed. The spectrafluorometric study of amino acid metal complexes shows that excitation wave length decrease with decrease in the polarity of medium. The amino acid nickel (II) complex exhibits a strong fluorescence emission at 340 nm in water medium. This may be tentatively assigned to the ligand to metal charge transfer (LMCT). In these complexes the amino acid coordinated to 1:2 with metal and they exhibits octahedral geometry. The catalytic activities of these complexes were studied in olefins using eco-friendly nontoxic molecular oxygen as oxidant.
