Study of the Products of the Interaction of Cobalt(II) Acetate with 2-Iodoterephthalic Acid and 1,10-Phenanthroline

A B S T R A C TIn the present work, the interaction of cobalt(II) acetate with 2-iodoterephthalic acid and 1,10-phenanthroline (phen) in N,N-dimethylformamide (DMF) was studied. The reaction leads to the formation of two products: hexa­kis­(N,N-di­methyl­formamide-κO)cobalt(II) bis­­(iodide) (compound 1) and MOF [Co(TP)(phen)·2DMF·2H2O] (compound 2), where TP is terephthalate dianion. Compound 1 crystallizes in the monoclinic space group Р2 1/с with cell parameters a = 14.2974(4) Å, b = 10.7983(4) Å, c = 20.6437(9) Å, V = 3183.23 Å3. The MOF was characterized by elemental analysis, infrared spectrometry, X-ray diffraction, scanning electron microscopy, thermogravimetry and volumetric nitrogen adsorption/desorption. The sample has permanent porosity and a microporous structure with a large surface area corresponding to the adsorption type I. Thermolysis of MOF leads to the formation of nitrogen-doped carbon nanomaterials Co/CoO@C.
