Abstract
A calixarene-based compound {[Co4(H2O) (TC4A-SO2)]4(DTB)8} (H4TC4A-SO2 = p-tert-butylsulfonylcalix[4]arene; H2DTB = 1,3-bis(2H-tetrazol-5-yl)benzene) was obtained under solvothermal condition. The compound was characterized by single crystal X-ray diffraction, elemental analysis, TG analysis and FT-IR spectroscopy. In the structure, the Co4-(TC4A-SO2) shuttlecock-like secondary building units (SBUs) are bridged by the DTB ligands into some window frame-like squares, which are further stacked into an extended structure by supramolecular interactions. The results of magnetic measurements indicated an antiferromagnetic interaction between the metal centers. In order to evaluate its porosity, the gas sorption measurement was carried out.
