A Cuboidal Tetranuclear Nickel Cluster Based on O,O,N-Tridentate Schiff Base: Synthesis, Structure and Magnetic Properties

摘要

One tetranuclear nickel cluster [Ni4L4(CH3CH2OH)(4)] (1, H2L = N-(2-hydroxyphenyl)salicylaldimino) was synthesized by solvothermally reaction and characterized by elemental analysis, IR, TGA and X-ray single-crystal diffraction. It exhibits a cubane-type [Ni4O4] structure with four Schiff base ligands and four alcohol molecules in the unit. Magnetic susceptibility studies indicate that there are ferromagnetic interactions within the tetranuclear nickel(II) cluster. Furthermore, Thermogravimetric analyses display the stability of complex 1.
