Two manganese complexes, [MnII4MnIII6Cl4(CH3OCH2CH2O)12 O4][MnII3TiIVCl6(CH3OCH2CH2O)6] (1) and [MnII4MnIII6Cl4(CH3OCH2CH2O)12O4] [Mn4II Cl10(CH3OCH2CH2OH)4]∙0.5CH3OCH2CH2OH, (2) have been obtained and characterized by single-crystal X-ray diffraction. Both structures consist of the decametallic dicationic [MnII4MnIII6Cl4(CH3OCH2CH2O)12O4]2 + core constructed by four vertex-sharing [MnIII3MnIIO]9 + tetrahedra. Also, these compounds contain the different tetrametallic dianions: [MnII3TiIVCl6(CH3OCH2CH2O)6]2 − (in complex 1) and [Mn4IICl10(CH3OCH2CH2OH)4]2 − (in complex 2). Magnetic dc and ac susceptibility measurements for compound (1) show that the dicationic decanuclear magnetic cluster possesses an S = 12 ± 1 spin ground-state.
