| Abstract: | Two new coordination polymers with 3-pyridyl-4-yl-benzoic acid (3,4-HPybz), namely, Zn(3,4-Pybz)2 · 2H2O] n (I) and Ag(3,4-Pybz)(3,4-HPybz)] n (II), have been synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, and single crystal X-ray diffraction. Compound I crystallizes in the triclinic system and has P1 space group. Complex I is an infinite 1D chain polymer and the infinite chains array uniformly in a 3D supramolecular network which posesses abundant O-H...O hydrogen-bonding interactions among the occupied and unoccupied carboxylate O atoms and the coordinated water molecules; compound II crystallizes in the triclinic system and has $P\bar 1$ space group, II is an infinite chain with the repeat sequence of Ag1(I)-Ag2(I)-Ag1(I), in which weak intermolecular interactions play a key role in forming the final 3D supramolecular architectures. The photoluminescences and lifetime of I and II in the solid state have been investigated. |
