Compound [Mn6 (O)2 (PhCO2)10 (py)2 (MeCN)(H2O)]·0.5CH3OH·1.5H2O (1·0.5CH3OH·1.5 H2O) is obtained as the aggregation product of the simple manganese triangle [Mn3O(O2 CPh)6 (py)2 (H2O)]. X-ray structural analysis reveals that compound 1 contains a [Mn6O2]10+ core that can be conveniently described as two edge-sharing Mn4 tetrahedron at the center of each of which is a μ4-O2- ion. Peripheral ligation to the octahe-drally coordinated Mn centers is provided by ten benzoates, two pyridines, one aeetonitrile and one water molecule. The complex is mixed valence (Mn4Ⅱ Mn2Ⅲ) according to the structure analysis. Variable temperature susceptibility measurement of compound 1 reveals that dominant antiferromagnetic interactions are propagated between the mag-netic centers.
