Synthesis and Characterisation of Antifungal Agents Containing Copper(II) Soaps and Derived from Mustard and Soyabean Oil

Abstract The solid copper(II) soaps derived from Mustard oil and Soyabean oil and their complexes with ligands containing nitrogen and sulphur atoms like urea, thiourea and 2-amino-6-chloro benzothiazole have been synthesized and characterised by elemental analysis, IR, NMR, ESR spectroscopy and magnetic moment studies. From the analytical data, the stoichiometry of the complexes have been observed to be 1: 1 (metal: ligand). The magnetic moment studies suggest the dimeric nature of the complexes. IR, NMR and ESR spectral details confirm that complexation has taken place successfully. The results indicate that the complexes possess elongated octahedral geometry. Conductometric studies suggest that the soaps and complexes are non-electrolytic in nature. The fungi toxicities of these ecofriendly and biodegradable soaps and complexes have been investigated.
