Benzenedicarboxylic Acid

The coordination polymer, namely, [Cd(H2L)(nobda)]n (1) was prepared by the reaction of Cd(NO3)2·4H2O with 4-amino-1,2-benzenedicarboxylic acid (H2nobda) and 1,4-di(1H-imidazol-4-yl)benzene (H2L), and characterized by single-crystal X-ray diffraction, elemental analysis, infrared (IR) spectroscopy, thermogravimetric analysis, and powder X-ray diffraction (PXRD). The carboxylic acid of H2nobda ligands was completely deprotonated to be nobda2− anions, which act as tridentate ligand to connect the Cd2+ to form two-dimensional (2D) network, while the neutral H2L ligands serve as a linear didentate bridge to connect two adjacent Cd2+ ions upper and down the 2D layer. The adjacent 2D layers were further linked into the three-dimensional (3D) supramolecular polymer by the weak interactions such as hydrogen bonds and π−π stacking interactions. The ultraviolet-visible (UV-vis) absorption spectra and luminescent properties in the solid state at room temperature have been investigated.

Abstract A novel 1D zinc(II) coordination polymer [Zn(absa)- (pcih)](CH3OH) (1) (Habsa = 4-aminobenzenesulfonic acid, Hpcih = 2-pyridinecarbaldehyde isonicotinoylhydrazone) has been synthesized by solvothermal reaction at 72 °C and structurally characterized. Each Zn2+ ion is five-coordinated by three N atoms and one O atom from two pcih ligands, and one O atom of an absa ligand, forming a distorted squarepyramidal geometry. Zn2+ ions are bridged by pcih ligands in a zig-zag arrangement generating infinite chains with appended absa ligands. Photoluminescent studies have shown that 1 exhibits an emission at 535 nm (λex = 492 nm).

A chain Ni (II) coordination polymer material was prepared and characterized by elemental analysis and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2/c with a = 1.24348(13) nm, b = 1.29477(12) nm, c = 1.51480(17) nm and Dc = 1.401 g•cm-3. The results of structural analysis indicated that each Ni (II) ion forms six-coordinated with nitrogen atoms of pyridine and thiocyanate, and the Ni (II) coordination polymer material formed one dimensional chain structure by the interaction of pyridine rings.
