title: Solution structure of a seven coordinated manganese(II) complex via electrospray ionization mass spectrometry.
abstract: The mononuclear complex [Mn(tptz)(CH(3)COO)(OH(2))(2)]NO(3) (1) was investigated by electrospray ionization mass spectrometry in aqueous solution at pH 4.5. Electrospray ionization mass spectrometry shows that mononuclear and dinuclear manganese cationic species are present in solution, probably in equilibrium with neutral 1. An experiment showed that the most important reaction in the presence of oxone (2KHSO(5).KHSO(4).K(2)SO(4)) is decoordination.
