A crystalline solid, formed by oxidation of phthalocyanatomanganese(II) in pyridine, has been identified as phthalocyanatopyridinemanganese(III)-µ-oxo-phthalocyanatopyridinemanganese(III)dipyridinate(C74H42Mn2N18O2C5H5N) byx-ray diffraction methods. This novel molecule consists of two manganese complexes joined by an essentially linear Mn—O—Mn bridge. Its structure may have some relation to oxidation processes in biological systems.
