Abstract

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 [Mn^III 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 Mn^II(H₂O)₄ fragment. In both compounds, a moderate intracluster MnIII£Mn^III ferromagnetic interaction was observed. It was also found that the Mn ^III₃O₄ cluster cores are maintained in solution.
