Abstract :
Mono- and dinuclear nickel(II) complexes with N3O asymmetrical Schiff bases have been prepared and characterised. The ligands used here were obtained by condensation of the amine 7-amino-4-methyl-5-aza-3-hepten-2-one (HAE) and 4(5)-imidazolecarboxaldehyde or 2-acetylpyrazine, to yield the isolated Schiff bases H2AE4(5)Im and HAEPyz, respectively. Physicochemical data (mean) indicate that all the complexes are quasi square planar. The X-ray crystal structure of [Ni(AEPyz)]ClO4 is reported, whose NiN3O cromophore is remarkably square planar.
