Abstract
Reaction of Mn(ClO4)2 . xH2O and Mn(CH3CO2)3 . xH2O with 2,2': 6',2'': 6'',2'''-quaterpyridine (QP) in acetonitrile or methanol gave the com plexes [Mn(QP)(H2O)2] (ClO4)2 and [Mn(QP)(CH3CO2)(H2O)](ClO4), respect ively. X-ray crystal structure determination revealed that the mangane se atom is six-coordinated in the former, but seven-coordinated in the latter. Both complexes catalysed oxidation of alkenes by PhIO.
