A thioether-decorated {Mn11Tb4} coordination cluster with slow magnetic relaxation

Abstract

The oxidation reaction of manganese(II) acetate tetrahydrate with terbium(III) nitrate hexahydrate in acetonitrile in the presence of 4-(methylthio)benzoic acid (Hbza·SMe) afforded a polynuclear [MnIII11TbIII4O9(OH)5(bza·SMe)18(NO3)2(H2O)6(OMe)2] complex (1) with a {Mn5Tb2O6}-bridged double-{TbMn3O4}-cubane structure. This antiferromagnetically coupled, neutral molecule is decorated in the periphery with structurally exposed thioether groups which can be used as anchors to metallic surfaces. Compound 1 is potentially a single-molecule magnet (SMM), exhibiting slow relaxation of the magnetisation up to 3 K. While 1 is not thermally stable, the coordination cluster remains stable in various Lewis base-type organic solvents like THF and acetone.
