Abstract

Abstract: The reaction of cobalt(II) acetate with 2-iodoterephthalic acid and 1, 10-phenanthroline (phen) in N, N-dimethylformamide (DMF) leads to formation of two products, hexakis(N, N-dimethyl-formamide-κO)cobalt(II) bis(iodide) (1 ) and MOF [Co(TP)(phen)·2DMF·2H2 O] (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 Å 3 . 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 2 leads to the formation of nitrogen-doped carbon nanomaterials Co/CoO@C. Graphical Abstract:
