Synthesis and spectroscopic studies on nickel [II] complexes of the tetradentate ligand n,n' -di-3- [4,5-dimethylpyrazolyl formyl] hydrazone

ABSTRACT

N,N'-di-3-[[4,5-dimethylpyrazolyl] formyl] hydrazone, L, reacts with nickel [II] salts to form 1 1 and 1 2 complexes. The 1 1 binuclear systems involve 2 ligands bridging 2 metals, in which L behaves as a tetradentate ligand, and the nickel ions have a pseudo- octahedral stereochemistry. These complexes were formulated
