Abstract
Abstract A novel metal–organic complex [Fe(H2bpdc)]SO4 (1) has been hydrothermally synthesized (H2bpdc = 2,2'-bipyridyl-5,5'-dicarboxylic acid) and structurally characterized by elemental analyses, IR spectra, powder X-ray diffraction and single-crystal X-ray diffraction, which displays the first 1-D ferrous sulfate chain functionalized by H2bpdc. Interestingly, the 3-D supramolecular structure of 1 can be constructed by means of hydrogen-bonding interactions and Fe···O short contacts. Thermogravimetric analysis indicates that 1 shows a good thermal stability and can be thermally stable up to 420 °C. Magnetic measurements of 1 exhibit the existence of antiferromagentic interactions within the FeII centers.
