What happens when (1H-benzimidazol-2-ylmethyl)-N-phenyl amine is added to copper(II) acetate? Spectroscopic, magnetic, and DFT studies.

Highlights: [•] Binuclear and polynuclear CuII acetate complexes were prepared. [•] Strong anti-ferromagnetic behavior was observed. [•] Presence of another bridging ligand altered the magnetic behavior. [•] Anionic effect was established by comparison with the chloro complex. [•] Correlation between experimental and theoretical data was performed. [Copyright &y& Elsevier]
