Self-assembly of a Linear Ni9 Triple-helical Supramolecule with Dominant Ferromagnetic Interactions.
A linear triple-helical supramolecule Ni9 L6 has been prepared through a controllable self-assembly approach using 1,3-bis-(3-oxo-3-phenylpropionyl)-2-hydroxy-5-methylbenzene (H3 L) and Ni(OAc)2 under solvothermal conditions. Single-crystal X-ray diffraction analysis confirms the axial C3 symmetrical helical structure of the product and the temperature-dependent magnetic susceptibility corresponds to a typical shape of a paramagnet showing dominant ferromagnetic exchange couplings between the neighboring Ni(II) ions.
