A novel tetra dentate macro cyclic ligand viz.

l, 5, 8, 13-tetraaza-2, 9-dimethyl-4, ll-diphe-nylcyclotetradeca-2, 4, 9, ll-tetraene (L) and its complexes with Pd11, Pt11, Rh111 and Ir111 metal ions were synthesized.

These complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, IR and electronic spectral studies.

On the basis of molar con-ductance and elemental analyses the general stoichiometries of the complexes were found to be [M (L)]C12 and [M'(L)CI2] CI, where M = Pd(II), Pt(II) and M' = Rh(III), Ir (III).

The spectral studies reveal the four coordinated square planar geometry for Pd" and Pt" complexes and six coordinated octahedral geometry for Rh™ and Ir111 complexes.

In vitro the synthesized ligand and its metal complexes have been screened for bactericidal and fungicidal activities using disc diffusion and food poison technique, respectively, at different concentrations.

The organisms used in antibacterial investigation included Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and for antifungal investigation Aspergillus-niger, Aspergillus-glaucus, Fusarium odum.

The antimicrobial data reveal that the metal complexes act more as bactericidal and fungicidal agents as compared to the uncomplexed ligand and the metal salts from which they derive.
