Abstract

Four distinct polynuclear Ni(II) complexes, namely [Ni₂L₂(py)₂] (1), [Ni₃L₂(μ₃-OAc)₂]·4CH₃CN (2), [Ni₄L₂(μ₂-OAc)₂(μ₃-OMe)₂(H₂O)₂]·MeOH (3), and [Ni₇L₃(μ₃-OMe)₂(μ₃-OH)₆(MeOH)₆] (4), have been synthesized and characterized based on the salamo Schiff base ligand H₂L. Ultraviolet–visible titration experiments and time-dependent density functional theory calculations elucidated that different reaction conditions (solvents and the metal–ligand molar ratio) result in the formation of these polynuclear structures. Magnetic investigations revealed the presence of intramolecular ferromagnetic coupling between Ni(II) centers in complexes 2–4.

期刊介绍： The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials. Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
