摘要	The employment of the hydroxyl-rich ligand (E)-3-((2-hydroxy-3-methoxybenzylidene)amino)propane-1,2-diol (H3L) in the chemistry of cubane-type {M4O4} clusters is reported. Three cubane-type clusters of the formula [M-4(HL)(4)] (M = Co-II (1), Zn-II (2), Cu-II (3)) were achieved by reactions of metal acetates with H3L under solvothermal conditions. The structures of 1, 2 and 3 have been established by single-crystal X-ray diffraction studies. The tetranuclear clusters 1-3 have cubane-type [M-4(mu(3)-OR)(4)](4+) cores with divalent metal atoms and deprotonated oxygen atoms (originating from the HL2- ligands) occupying alternate vertices. The luminescence studies suggest strong emission for 2 in the solid state at room temperature. The magnetic properties of 1 and 3 have been investigated. The variable-temperature dc magnetic susceptibility studies indicate ferromagnetic M-II ... M-II exchange interactions for 1 and 3. The ac magnetic susceptibility investigation reveals that complex 1 shows slow magnetic relaxation (SMM) behavior.
