Abstract
Tetradentate complexes of Zn (II) of Schiff bases derived from DHA, o-phenylenediamine, 4- N, N, Diethyl amino Salicylaldehyde (L1) and Dehydroacetic Acid (DHA), 4-methyl-o-phenylenediamine, 5-bromo Salicylaldehyde (L2) have been synthesized and characterized by elemental analysis, magnetic susceptibility, thermal analysis, X-ray diffraction, 1HNMR, Mass, IR,UV visible spectra and conductometry. The ligand field parameters have been characterized and found to have octahedral geometry. Thermal behavior (TG/DSC) of the complexes was studied. X-Ray diffraction study reveals monoclinic crystal system. The ligand and its complexes were subjected for antibacterial activity against Escherichia coli and Staphylococcus aureus and fungicidal activity against Trichoderma and Aspergillus Niger.
