Abstract:

Coordination polymer ZnCo(BTC)(OH)(H2O)3(NMP)(DMF)(H2O)1.5 was synthesized by slowly diffusing a balanced amount of organic amine into a solution of 1,3,5-benzenetricarboxylate(H3BTC), zinc nitrate and cobalt nitrate. X-ray single crystal diffraction shows that the compound crystallizes in cubic, space group P213, and its cell parameter is 1.43863(20) nm. Its physical properties were characterized by elemental analysis(EA), energy-dispersive X-ray spectroscopy(EDS), X-ray powder diffraction(XRD), N2 sorption and variable-temperature magnetic susceptibility. The gas sorption shows this compound holds Ⅰ-isotherm characteristic of micropore, which is 0.84 nm of pore size and 832 m 2/g of langmiur surface area. The magnetic results show that it exhibits antiferromagnetism in the temperature range of 37—300 K.
