Self-assembly of a Linear Ni9 Triple-helical Supramolecule with Dominant Ferromagnetic Interactions

A linear triple‐helical supramolecule Ni9L6 has been prepared through a controllable self‐assembly approach using 1,3‐bis‐(3‐oxo‐3‐phenylpropionyl)‐2‐hydroxy‐5‐methylbenzene (H3L) and Ni(OAc)2 under solvothermal conditions. Single‐crystal X‐ray diffraction analysis confirms the axial C3 symmetrical...

Summary:A linear triple‐helical supramolecule Ni9L6 has been prepared through a controllable self‐assembly approach using 1,3‐bis‐(3‐oxo‐3‐phenylpropionyl)‐2‐hydroxy‐5‐methylbenzene (H3L) 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 NiII ions. Linear story: A linear Ni9 triple‐helical supramolecule with an axial C3 symmetrical helical structure has been prepared through a controllable self‐assembly approach under solvothermal conditions. The existence of dominant ferromagnetic exchange couplings has been found between the neighboring NiII ions.
