SPECTRO-ANALYTICAL EVALUATION OF NEW HYDRAZONE SCHIFF BASE AND ITS DIVALENT COPPER (II) COMPLEX AND FLUORESCENCE STUDY

The divalent metal complexes of [Cu(II)(L)(H₂O)₂] was obtained by the reaction of new hydrazone Schiff base ligand of heterocyclic 2-hydroxybenzylidene)-4-oxopiperidine-1-carbohydrazide (H₂L). The metal (II) complex was analyzed and characterized by elemental analysis, some routine spectral techniques viz., FT-Infrared, UV-visible spectroscopy, and powder XRD. The stoichiometric ratio of hydrazone ligand and its Cu(II)metal was observed as 1:1 (M:L) in the complex. The spectral, TG data suggested a tetrahedral structure of Cu(II) complex.

KEYWORDS: Hydrazone Schiff base, divalent metal complex, spectral characterization, fluorescence emission, antifungal and anti-bacterial study.
