ANTI- FUNGAL PROPERTIES OF SYNTHESIZED COMPLEXES OF TRIVALENT TRANSITION METAL IONS DERIVED FROM INDAN-1, 3-DIONE AND DIAMINOBENZENE

Macrocyclic ligands and their metal complexes are being synthesized very fast as it is a developing area of research in bioinorganic and inorganic chemistry. A new series of trivalent chromium, cobalt and iron complexes have been prepared through template methods with 2, 2-dihydroxyindane1, 3-dione and isomeric diaminopyridines and effectiveness towards anti fungal properties of these complexes is studied against the cotton plant fungi, Alternaria alternata and Fusarium oxysporum. The complexes have been characterized by elemental analyses, molar conductance, electronic spectra, 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 ohmcm mol). Indofil M-45 and bavistin are the standard fungicides which are used to compare the anti-fungicidal properties of the synthesized complexes. Some of the complexes have been found to be antifungal in nature.
