摘要
The reaction of Co(ClO4)(2)center dot 6H(2)O with 2-hydroxy-3-methoxy-benzaldehyde and an aqueous solution of methylamine in acetonitrile/MeOH under microwave irradiation and controlled temperature/pressure leads to formation of heptanuclear cobalt cluster [Co-7(mmp)(6)(CH3O)(6)]center dot(ClO4)(2) (1) (mmp is 2-methoxy-6-methyliminomethyl-phenol anion) in only 20 min and also results in higher yields in contrast to other synthesis methods. Complex 1 displays dominant ferromagnetic interactions through mu (3)-O and mu (2)-O (oxidophenyl) binding modes.
