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.

A new coordination polymer, namely, [Cd(L)(frda)(H2O)]·0.5L·H2O (1) was synthesized by hydrothermal reaction based on mixed multi-N donor 1-(4-(1H-imidazol-5-yl) phenyl)-1H-1,2,4-triazole (L) and O-donor 2,5-furandicarboxylic acid ligands (H2frda) with CdCl2·2.5H2O. Compound 1 was characterized by single-crystal x-ray diffraction, elemental analysis, and IR spectroscopy. In 1, both the multi-N donor and O-donor frda2− ligands act as linear two-connectors to bridge Cd(II) atoms, forming a two-dimensional (2D) layer. Interestingly, the parallel 2D layers stack in an AAA···mode, and the infinite one-dimensional (1D) channels formed along the a-axis direction, where the uncoordinated L molecules were embedded in the void. Furthermore, the weak interactions including the rich hydrogen bonding and π−π stacking interactions progress the 2D structure into a three-dimensional (3D) supramolecular polymer. Diffuse reflectance spectra and the luminescent property were also investigated.

The three-dimensional [Co3(OH)2(H2O)2(aptet)4] exhibits magnetic properties consistent with a ferrimagnetic chain with the non-compensating resultant moment of one Co(ii) per trinuclear Co(ii) subunit and ac magnetic susceptibility indicative of glassy-like magnetic behavior.

In poly[[μ3-2,2′-(disulfanediyl)dibenzoato-κ5 O:O,O′:O′′,O′′′](1,10-phenanthroline-κ2 N,N′)cadmium(II)], [Cd(C14H8O4S2)(C12H8N2)] n , the asymmetric unit contains one CdII cation, one 2,2′-(disulfanediyl)dibenzoate anion (denoted dtdb2−) and one 1,10-phenanthroline ligand (denoted phen). Each CdII centre is seven-coordinated by five O atoms of bridging/chelating carboxylate groups from three dtdb2− ligands and by two N atoms from one phen ligand, forming a distorted pentagonal–bipyramidal geometry. The CdII cations are bridged by dtdb2− anions to give a two-dimensional (4,4) layer. The layers are stacked to generate a three-dimensional supramolecular architecture via a combination of aromatic C—H...π and π–π interactions. The thermogravimetric and luminescence properties of this compound were also investigated.
