A new inorganic–organic hybrid material containing a neutral three-dimensional open framework: Synthesis and characterization of [{Co2(4,4′-tmdp)4}V4O12] (4,4′-tmdp = 4,4′-trimethylenedipyridine)

Hydrothermal reaction of NH4VO3, CoSO4 · 7H2O, 4,4′-trimethylenedipyridine (4,4′-tmdp = C13H14N2), and H2O yielded a new hybrid species, [{Co2(C13H14N2)4}V4O12], containing arrays of {V4O12} rings covalently linked through metal-organic units, {Co(C13H14N2)2}, into a three-dimensional open-framework structure. The novel material has been characterized by single crystal X-ray diffraction, infrared spectroscopy, elemental analysis, thermogravimetric analysis, and magnetic susceptibility measurement. The new material is potentially an attractive model compound for studying the structures of metallo-organic biomolecules by solid state NMR spectroscopy.

A neutral framework composite containing arrays of {V4O12} motifs covalently linked through {Co(C13H14N2)2} units has been synthesized and characterized. The new material is an attractive model system for studying the structures of metallo-organic biomolecules in living organisms by using solid state NMR spectroscopy.Figure optionsDownload as PowerPoint slide
