A New Tetranuclear Cubane-like Ni(Ⅱ) Complex Based on Schiff-base Ligand: Synthesis,Crystal Structure and Magnetic Properties

A new Ni(Ⅱ) cubane-like complex, namely, Ni(L)(CH_3OH)]_4·(CH_3OH)_2, has been obtained via self-assembly of nickel(Ⅱ) and Schiff base, where the ligand L is a raceme of(R)-2-(2-hydroxy-1-phenyl-ethylimino)-methyl]-6-methoxy-phenol. X-ray diffraction analysis reveals that the complex shows a cubane-like Ni_4O_4] cluster and similar coordination environment around the metallic centers. Magnetic measurements indicate there is ferromagnetic interaction within the Ni_4 cluster.
