A Cu(II) complex of a ligand [L] derived from salicyloyl hydrazide and furfuraldehyde has been prepared. The ligand and metal complex were characterised by elemental analysis, magnetic measurement, molar conductance, FTIR, UV-Vis spectra, ESR and mass spectral studies. Analytical data suggests the molecular formula of the complex as [CuL2]Cl2. The IR spectral data suggest that the [L] is acting as neutral bidentate ligand towards Cu(II) in its complex.IR, ESR and magnetic susceptibility of the sample taken in the solid state, electronic and mass spectra are taken in the ethanolic solution and the conductance is measured in the solution state. The electronic spectral data and magnetic moment value agrees to the tetrahedral geometry of the complex. The electrolytic nature is evidenced from the high conductance data. The biological screening activity of the ligand and its copper(II) complex against the bacteria Escherichia Coli, Vibreo Cholerae and fungi Aspergillus Niger, and Penicillium Crysogenum are also reported. The complex exhibit increased activity than the ligand.
