摘要：

A new tetranuclear mixed-valence manganese(II/IV) compound [(MnMn3IV)-Mn-II(mu-Cl)(3)(mu(3)-O)(L)(3)] (1) (where H3L = (3E)-3-((Z)-4-hydroxy-4-phenylbut-3-en-2-ylideneamino)propane-1,2-diol) has been synthesized and characterized by different physicochemical methods. Single crystal X-ray diffraction analysis reveals that 1 is a tetrahedral cluster consisting of a Mn4Cl3O4 core in which the only Mn(II) ion is joined through three mu(2)-O bridges to an equilateral triangle of Mn(IV) ions, which are connected by a mu(3)-O and three mu(2)-Cl bridges. The redox behavior of 1 was studied by cyclic voltammetry. Variable temperature magnetic susceptibility measurements of 1 revealed predominant antiferromagnetic coupling inside the Mn4Cl3O4 cluster.
