4. Conclusion
The azodye behaves as an O N donor bidentate ligand and
forms octahedral complexes with CoII and NiII complexes, distorted-octahedral
complex with CuII complex and tetrahedral
complexes with ZnII, CdII and HgII complexes. The NiII complex
is found to possess an orthorhombic crystal system. All
calculations based on molecular mechanics on the optimised
geometries of the ligand and the complexes agree with the
experimental results obtained from electronic spectral analysis
and XRD study. The ligand as well as CoII , NiII , CuII and
ZnII complexes are found to possess a strong antibacterial
activity against both gram positive and gram negative bacteria
and hence may be used as chemotherapeutics drugs for the
cure of infectious diseases.
