Guest-accessible channels are located in the internanorod space generated by the self-assembly of the nanorodlike constructs via complementary hydrogen bonding. Thus, reaction of a hydrogen-bond-equipped and conformationally flexible ligand such as <i>N</i>,<i>N</i>‘-bis(3-pyridyl)urea with CuSO<sub>4</sub> resulted in the formation of a stable, guest-free microporous MOF wherein a nanorodlike construct is formed that is further self-assembled into a microporous metal−organic framework via self-complementary hydrogen bonding involving a urea backbone and sulfate anion. Because of conformational flexibility, a one-dimensional zigzag coordination polymeric network is also formed. The structures are characterized mainly by single-crystal X-ray diffraction techniques.
