Abstract

Two tetranuclear Ni(II) clusters, [Ni(L¹)(µ₃-OCH₃)(CH₃OH)]₄·5CH₃OH (1) and [Ni(L²)(µ₃-OCH₃)(CH₃OH)]₄ (2) (HL¹ = methyl 2-hydroxy-3-methoxybenzoate; HL² = 4-(1,1,3,3-tetramethylbutyl)phenyl salicylate) were synthesized and characterized by X-ray crystallography and magnetic properties. Both complexes have [Ni₄O₄] cubane cores assembled with four triply-bridged methoxy oxygens. The temperature-dependent magnetic susceptibilities for 1 and 2 show ferromagnetic interactions between Ni(II) ions. The best fit parameters for their magnetic behaviors are J₁ = + 9.32 cm⁻¹, J₂ = − 1.66 cm⁻¹ and g = 2.24 for 1, and J₁ = + 9.82 cm⁻¹, J₂ = − 1.98 cm⁻¹, g = 2.21 for 2, respectively.
