Abstract: | Summary 4N-diethyl- and4N-dipropylthiosemicarbazones of 2-acetylpyridine coordinate to FeIII, CoIII and CoII centres as tridentate NNS ligands. Spectral and physical data indicates that the size of the4N-substituents can influence the stereochemistry and stoichiometry of the complexes, which show minimal ability to inhibit fungal growth and are considerably less active than the related copper(II) and nickel(II) complexes. |
