In the present study Schiff base and Cu (II) complex have been synthesized and reported. The Schiff base is prepared by condensing 2-aminopyridine and 9-anthraldehyde. The complex was synthesized by reaction of CuCl2.2H2O with Schiff base. These compounds have been characterized byelemental analysis, magnetic measurement, molar conductance, FT-IR, UV-Vis spectra, 1H NMR, electronic, mass and ESR spectroscopic studies. Analytical data suggests the molecular formula [Cu(L)2Cl2] for Cu(II) complex. The IR spectral data suggest that Schiff base acts as a neutral monodentate ligand towards Cu(II) in its complex. The electronic spectral data and magnetic moment value agree with the tetrahedral geometry for the complex. The Schiff base and complex were screened for antibacterial and antifungal studies. The Cu(II) complex exhibit increased antimicrobial activity than Schiff base.
