摘要

The three-dimensional (3D) inorganic-organic hybrid framework cobalt phosphite (C_2H_6N)[Co_(1.5)(OH)(HPO_3)] (CoHPO-CJ10) was synthesized hydrothermally. Its structure is constructed by the connection of CoO_6 octahedra, CoO_5N octahedra, HPO_3 pseudo-pyramids, and 1,4-butanediamine molecules. It exhibits a pillared-layer structure with an unusual Co/P ratio of 3/2. The 1,4-butanediamine molecule acts as a pillar to link the adjacent cobalt phosphite layers to form open framework. Interestingly, such structure contains infinite edgesharing connected Co-O-Co chains, that are rarely occurred in the structures of cobalt phosphates/phosphites. It was characterized by single-crystal X-ray diffraction, X-ray powder diffraction (XRD), infrared (IR) spectra, UV/Vis spectroscopy, thermal gravimetric analyses (TGA), inductively coupled plasma (ICP), X-ray photoelectron spectroscopy (XPS), and elemental analyses. It exhibits antiferromagnetic interaction.
