Abstract
The synthesis and structure of the first extra-large pore cobalt phosphite (CoHPO-CJ2) with one-dimensional channels bounded by 18 Co atoms were presented. CoHPO-CJ2 was synthesized by a solvothermal reaction of CoCl 2.6H20, H3PO3, diethylenetriamine (DETA), ethylene glycol (EG), and H2O. CoCl2.6H 20 was first dissolved in a mixed solvent of H2O and EG, and then H3PO3 was added to the reaction mixture while stirring. DETA was added to adjust the pH value of the reaction mixture to 5-6. The use of mixed solvent favored the formation of large single crystals of CoHPO-CJ2. Each Co(1)O6 octahedron shared a face with the neighboring windmills, resulting in an infinite 2D layered structure with 18-ring window of C3v symmetry. Single crystal structural analysis reveals that the structure of CoHPO-CJ2 consists of macroionic framework and H3O+ counterions.
