SYNTHESIS AND CHARACTERIZATION OF TETRANUCLEAR MANGANESE(III) COMPLEXES WITH 2,6-BIS(SALICYLIDENEAMINOMETHYL)-4-METHYLPHENOL

Tetranuclear manganese(III) complexes with 2,6-bis(salicylideneaminome thyl)-4-methylphenol (H(3)L), [Mn-4(L)(2)(O)(2)(CH3COO)(2)]. 2CH(3)CN (1) and [Mn-4(L)(2)(O)(2)(C6H5COO)(2)]. 2CH(3)OH (2), have been synthe sized and characterized by infrared and electronic spectra, cyclic vol tammetry, and temperature dependence of magnetic susceptibilities (4-3 00 K). The molecular structure of 1 was determined by single-crystal X -ray structure analysis. Complex 1 has a tetranuclear structure, in wh ich two incomplete cubanes are sharing faces by the ore-bridges. The m agnetic susceptibility data show an overall antiferromagnetic interact ion.
