Abstract

ABSTRACT New bis (bidentate) azine NNN'N'donor ligand was prepared by linking (1Z, 1'Z)- 1, 1'-{propane-1, 3-diylbis [oxybenzene-4, 1-diyl (1Z) eth-1-yl-1-ylidene]} dihydra-zine to pyridine-2-carbaldehyde. Two kinds of copper (II) and nickel (II) complexes with different stoichiometries were prepared. Reaction of bis (azine) ligand with Cu (II) and Ni (II) chloride with 1: 1 molar ratio gave azine complexes with stoichiometry [M (L) Cl 2] while 2: 1 molar ...
