|Abstract:||The terfunctional schiff base ligands acetylaceton-4aminoantipyrine, salicylal-4-aminoantipyrine and 2-hydroxy-1-naphthal-4-aminoantipyrine react with Cu(II) and Ni(II) metal ions in different stoichiometric ratios and at various pH values to yield complexes with different bonding features such as (i) neutral bidentate - coordination via. > C = 0 and > C = N-, (ii) neutral terdentate - coordination via. > C=O, =CH-NH- and quinonoid = O: from -OH, (iii) monovalent bidentate - coordination via. > C = N-, and -O- from -OH and (iv) monovalent terdentate coordination via. > C = N, > C = O and -O- from -OH.|
