Synthesis, structure and characterization of new 1D and 2D Ni(II) coordination polymers

Two new Ni(II) coordination polymers, namely [Ni3(Hsdac)2(sdac)2(2,2′-bipy)2] (1) and [Ni2(sdac)2(4,4′-bipy)2]·2H2O (2) (sdba = 4,4′-sulfonyldibenzoate, 2,2′-bipy = 2,2′-bipyridine, 4,4′-bipy = 4,4′-bipyridine), have been prepared under hydrothermal conditions and characterized by single crystal X-ray diffraction analyses. Compound 1 possesses an interesting chain structure. Adjacent chains are further linked through H-bond interactions between Hsdac ligands to give a two-dimensional (2D) supramolecular architecture. Compound 2 displays an unusual 2D polyrotaxane-like network.

Two new Ni(II) coordination polymers have been successfully prepared under hydrothermal conditions through varying the secondary ligands, and structurally characterized by X-ray crystallography.Figure optionsDownload as PowerPoint slide
