The Schiff bases have been synthesised by the reaction of Benzoinoxime primary ligand with heterocyclic compounds such as 2-aminothiazole (SL₁) and 8-hydroxyquinoline (SL₂) to form the secondary ligand, which than react with the metal halides to form complexes of Co (II) and Zn (II). The elemental analysis data shows that the metal to ligand ratio in all Co (II) simple is 1:2 for simple complexes and 1:2:2 for metal complex with oxime as a primary ligand and SL₁ as a secondary ligand while it is 1:2:1 for metal complex with oxime as a primary ligand and SL₃ as a secondary ligand whereas Zn (II) complexes of mixed ligand exhibit the stoichiometry 1:2:2. The structural features have been determined from IR, UV-Vis, and XRD data. All the complex shows a distorted octahedral geometry to mononuclear Co (II) complexes of mixed ligands, while square planner geometry to mononuclear Co (II) complexes of oximes. Zn (II) complexes of mixed ligands shows a distorted octahedral geometry, while square planner geometry to mononuclear Zn (II) complexes of oximes.  All the synthesised compounds were screened for antimicrobial activity.
