SYNTHESIS, CHARACTERIZATION, THERMAL, X-RAY AND ANTIMICROBIAL STUDY OF ZN (II) METAL COMPLEXES OF DEHYDROACETIC ACID BASED NEW SCHIFF BASES

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