Ligational Behavior of Tridentate Schiff Base towards Transition Metal Ions

The ligational behavior of Schiff base ligand obtained by the condensation of cyanoacetylhydrazine and dehydroacetic acid towards some first transition series bivalent ions has been studied. The ligand on complexation yielded metal complexes of type ML2 where, L=anion of Schiff base ligand, cyano-acetic acid [1-(4-hydroxy-6- methyl-2-oxo-2H-pyran-3-yl)-ethylidene]-hydrazide; M=Co(II), Ni(II), Cu(II) or Zn(II)]. These complexes have been...
