Abstract:

Macrocyclic ligands and their metal complexes are being synthesized very fast as they are developing areas of research in bioinorganic and inorganic chemistry. A new series of trivalent chromium, cobalt and iron complexes has been prepared through template methods with 2, 2-dihydroxyindane- 1, 3-dione and isomeric diaminopyridines. The complexes have a tetra dentate ligand which coordinates to the metal ions through the nitrogen donor atoms. The structure of the complexes is mononuclear. Effectiveness towards anti fungal properties of these complexes is studied against cotton plant fungi: Alternaria alternata and Fusarium oxysporum. The complexes have been characterized by elemental analyses, molar conductance, electronic spectra, ESR, magnetic measurements and IR spectral data which points towards a distorted octahedral geometry. Conductivity measurements in dimethylsulphoxide indicated them to be 1:2 electrolytic in nature (130-170 ohm-1cm2 mol-1). Their fungicidal properties have been compared with the standard indofil M-45 and bavistin. Some of the complexes have been found to be anti-fungal in nature.
