A compendium of N-substituted hydrazone salts as well as  transition metal developments remained synthesized by benzaldehyde and its disubstituted isomeric derivatives i.e. 3-hydroxybenzaldehyde and 2-hydroxybenzaldehyde (Salicylaldehyde). The bidentate ligands synthesized 2-[(Z)-(2-phenylhydrazinylidene) methyl] phenol, (1E)-1-benzylidene-2-phenylhydrazine, Hydroxy {4-[(Z)-(-hydroxybenzylidene) amino] phenyl}, 3-[(Z)-(2-phenylhydrazinylidene) methyl] phenol and their Cd (II) and Zn (II) developments remained also organized. Completely the respective products were characterized as well as evaluated by means of analytical parameters and various spectral techniques like IR spectroscopy, UV visible spectroscopy, anti-oxidant and anti-bacterial assay as the Schiff bases were analysed to be very agile products which refers towards the novelty and main intent of this synthetic research work, as featured study of isomeric Schiff bases to get the proficient sequels for anti-bacterial and anti-oxidant values.

Keywords: Schiff bases, transition metal complexes, synthesis, Salicylaldehyde, IR spectroscopy, UV visible spectroscopy, anti-bacterial, anti-oxidant, and 3-hydroxybenzaldehyde.
