Synthesis and Characterization of Tetranuclear Manganese(III) Complexes with 2,6-Bis(salicylideneaminomethyl)-4-methylphenol

Tetranuclear manganese(III) complexes with 2,6-bis(salicylideneaminomethyl)-4-methylphenol (H3L), [Mn4(L)2(O)2(CH3COO)2]·2CH3CN (1) and [Mn4(L)2(O)2(C6H5COO)2]·2CH3OH (2), have been synthesized and characterized by infrared and electronic spectra, cyclic voltammetry, and temperature dependence of magnetic susceptibilities (4—300 K). The molecular structure of 1 was determined by single-crystal X-ray structure analysis. Complex 1 has a tetranuclear structure, in which two incomplete cubanes are sharing faces by the oxo-bridges. The magnetic susceptibility data show an overall antiferromagnetic interaction.
