Four Complexes of Cu (II) and Ni (II) Schiff bases have been prepared. The Schiff bases are derived by the reaction of Salisylaldoxime primary ligand with heterocyclic compounds such as 2-aminopyridine (S-L2), 2-2- bipyridine (S-L4) to form the secondary ligand, which than react with the metal halides to form corresponding complexes. The elemental analysis data shows that the metal to ligand ratio in all Ni(II) and Cu(II) simple complexes are 1:2 while for mixed ligand complexes having ratio 1:2:2 for S-L2 while it is 1:2:1 for S-L4. The structural features have been determined from IR, UV-Vis, and ESR data. All the complexes exhibit a distorted octahedral geometry to mononuclear Ni(II), Cu(II) complexes of mixed ligands, while square planner geometry to mononuclear Ni(II), Cu(II) complexes of oximes. All the synthesised ligands and their metal complexes were screened for antimicrobial activity
