A novel ligand containing sulfonic has been synthesized using 2-formylbenzenesulfonic sodium and 3-thiosemicarbazide as starting materials, and a Er (III) complex was synthesized. The ligand was characterized by element analysis and IR spectrum. The crystal structure of the Er (III) complex was determined by X-ray single crystal diffraction. The results showed that the compound was triclinic, with P-1, a = 1.0596(4) nm, b = 1.3700(5) nm, c = 1.8305(7) nm, V = 2.4726(16) nm3, Z=2, M r= 1244.42, De =1.671 g/cm3, T = 273(2) K, F (000) = 1270, R = 0.0517 and wR = 0.1124. The complex forms two-dimensional layered structure through hydrogen bonds and π-π stacking.

The N-heterocyclic ligand 2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole (imb) has a rich variety of coordination modes and can lead to polymers with intriguing structures and interesting properties. In the coordination polymercatena-poly[[cadmium(II)-bis[μ-benzene-1,2-dicarboxylato-κ4O1,O1′:O2,O2′]-cadmium(II)-bis{μ-2-[(1H-imidazol-1-yl)methyl]-1H-benzimidazole}-κ2N2:N3;κ2N3:N2] dimethylformamide disolvate], {[Cd(C8H4O4)(C11H10N4)]·C3H7NO}n, (I), each CdIIion exhibits an irregular octahedral CdO4N2coordination geometry and is coordinated by four O atoms from two symmetry-related benzene-1,2-dicarboxylate (1,2-bdic2−) ligands and two N atoms from two symmetry-related imb ligands. Two CdIIions are connected by two benzene-1,2-dicarboxylate ligands to generate a binuclear [Cd2(1,2-bdic)2] unit. The binuclear units are further connected into a one-dimensional chain by pairs of bridging imb ligands. These one-dimensional chains are further connected through N—H...O hydrogen bonds and π–π interactions, leading to a two-dimensional layered structure. The dimethylformamide solvent molecules are organized in dimeric pairsviaweak interactions. In addition, the title polymer exhibits good fluorescence properties in the solid state at room temperature.
