Two new cluster compounds having chiral incompletecubane- type Mn III3O4 cores were synthesized using (2S)-2-hydroxy-4-(salicylideneamino)butyrate (H2L-) and characterized by X-ray analysis as well as magnetic susceptibility and spectroscopic measurements. Compound 1 contains a [MnIII 3(L) 3(μ3-OMe)]- cluster anion, while compound 2 prepared in water has a heptanuclear structure bearing two [Mn III3(L)3(μ3-OH)]- clusters connected by a MnII(H2O)4 fragment. In both compounds, a moderate intracluster MnIII£MnIII ferromagnetic interaction was observed. It was also found that the Mn III3O4 cluster cores are maintained in solution.
