Abstract

AbstractHydrothermal reactions of Co(NO3)2·6H2O and Zn(NO3)2·6H2O with 1,4‐bis(4‐phenoxy)benzenedicarboxylic acid (H2bcpb) resulted in the formation of the coordination polymers [Zn(bcpb)(Py)]n (1), and [Co(bcpb)(Py)2]n (2), respectively. Their structures were studied by single‐crystal and powder X‐ray diffraction methods and further characterized by IR spectroscopy, elemental analyses, and thermogravimetric analyses (TGA). Single X‐ray diffraction analyses revealed that complex 1 has a 1D loop chain. Each repeated unit contains two carboxylate ligands and two SBUs (secondary building units), whereas complex 2 has a 2D 4‐connected sql sheet with point symbol (44.62). The complexes are further expanded to 3D supramolecular structures through non‐covalent bonding interactions. Besides, photoluminescent property of complex 1 was also investigated in the solid state at room temperature.
