terephthalic acid (p-H2bdc), 4,4′-(hexafluoroisopropylidene)bis(benzoic acid) (H2hfipbb), and 4,4′-sulfonyldicarboxylic acid (4,4′-H2sdb), respectively. The structures of the complexes were determined by X-ray single-crystal diffraction. Complex 1 is a 1D chain structure containing a one-dimensional channel along the a direction and is further extended via O–H⋯S hydrogen bonds and C–H⋯π stacking interactions
