Environmental Influence on the Single-Molecule Magnet Behavior of [MnIII6CrIII]3+: Molecular Symmetry versus Solid-State Effects

A new family of hetero-tri-metallic complexes [M(CuTb)]n (n = 1, 2, ∞; M = Co, Cr, Fe): synthesis, structure and tailored single-molecule magnet behavior

The synthesis, structural characterization and magnetic properties of a new family of hetero-tri-metallic complexes [M(CuTb)]_n (n = 1, 2, ∞; M = Co, Cr, Fe), exhibiting single molecule magnet behaviour have been reported.

Enhancing the ferromagnetic coupling in extended phloroglucinol complexes by increasing the metal SOMO–ligand overlap: synthesis and characterization of a trinuclear CoII3 triplesalophen complex

The better overlap of the SOMO with the central π-system in the CoII3 than in the CuII3 complex enhances the spin-polarization and thus the ferromagnetic coupling.

Crystallographic order and decomposition of [MnIII6CrIII]3+ single-molecule magnets deposited in submonolayers and monolayers on HOPG studied by means of molecular resolved atomic force microscopy (AFM) and Kelvin probe force microscopy in UHV

Monolayers and submonolayers of [MnIII6CrIII]3+ single-molecule magnets (SMMs) adsorbed on highly oriented pyrolytic graphite (HOPG) using the droplet technique characterized by non-contact atomic force microscopy (nc-AFM) as well as by Kelvin probe force microscopy (KPFM) show island-like structures with heights resembling the height of the molecule. Furthermore, islands were found which revealed ordered 1D as well as 2D structures with periods close to the width of the SMMs. Along this, islands which show half the heights of intact SMMs were observed which are evidences for a decomposing process of the molecules during the preparation. Finally, models for the structure of the ordered SMM adsorbates are proposed to explain the observations.

A truncated [MnIII12] tetrahedron from oxime-based [MnIII3O] building blocks

The use of the novel pro-ligand H₄L combining the complimentary phenolic oxime and diethanolamine moieties in one organic framework, results in the formation of the first example of a [Mn^III₁₂] truncated tetrahedron.

Switching from antiferromagnetic to ferromagnetic coupling in heptanuclear [Mt6Mc]n+ complexes by going from an achiral to a chiral triplesalen ligand

The heptanuclear complexes [(chand^RR)₂M^t₆{Fe^II(CN)₆}]²⁺ (M^t = Mn^III, Fe^III) exhibit ferromagnetic interactions due to a more efficient spin-polarization mechanism compared to the complexes [(talen^t-Bu2)₂M^t₆{M^c(CN)₆}]ⁿ⁺ with antiferromagnetic interactions.
