Summary
New complexes of NiII-containing dihydrazones derived from dehydroacetic acid as primary ligands and ammonia or pyridine as secondary ligand were prepared and characterized by elemental analysis, conductance, spectral and magnetic data. The dihydrazones react with NiCl2 in their enolic forms as bis-tridentate complexing agents, forming dinuclear dihydrazido-diamine-dinickel complexes with ammino co-ligands. The ammino complexes were treated with pyridine to give the pyridino complexes. Squareplanar geometries are proposed for all the complexes and preliminary studies show that they possess antifungal activity.
