Some Transition Metal Complexes Derived from the Heterocyclic Ligands 3-Methyl-4-Arylazopyrazole-5-Ones

Some planar and octahedral complexes of the sulphates of Cu(II) and Ni(II) with different 3-methyl-4-arylazo pyrazole-5-ones have been prepared.The complexes contain only one molecule of the ligand which functions as a bidentate donar coordinating through its carbonyl and azo group while the rest of the positions in the coordination geometry of metal are occupied by water molecules.The magnetic and electronic data of the complexes are discussed in the light of structures assigned.
