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　C-3　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.
