| Abstract: | Summary Nickel(II) complexes of four tridentate NNS Schiff base ligands, derived by condensing 2-acetyl-and 2-benzoylpyridine with S-methyl- and S-benzoyldithiocarbazate, have been prepared and characterized. The monoligated complexes, Ni(NNS)X] (NNS = anionic ligand; X = Cl, Br, NCS, I) are diamagnetic and square-planar, whereas the bis-ligand complexes, Ni(NNS)2] are paramagnetic and tetragonal. The Schiff bases are fungitoxic towards A. solani, F. equisetti and M. phaseolina (approaching the toxicity of the commercial fungicide Nystatin), but the nickel(II) complexes are less fungitoxic than the free ligands. |
