AbstractDinuclear Ni(II) macrocyclic complex A ([Ni2L1OAc]ClO4⋅CH3OH⋅H2O) and dinuclear Ni(II) acyclic complex B ([Ni2L2](ClO4)2) were synthesized by condensation between H2L (3,3′‐(ethane‐1,2‐diylbis(benzylazanediyl))bis(methylene)bis(2‐hydroxy‐5‐methyl‐benzaldehyde)) and different molar equivalent 1,3‐propanediamine in the presence of Ni(II) ions. The structures of complexes were characterized by IR spectroscopy, elemental analysis, electrospray mass spectra and X‐ray single crystal diffraction. In complex A, the Ni(II)‐Ni(II) di...
