A new two-dimensional (2D) coordination polymer, namely, poly[[diaqua[μ3-(S)-2-(benzylamino)succinato-κ4 N,O 1:O 1′:O 4]cadmium(II)] monohydrate], {[Cd(C11H11NO4)(H2O)2]·H2O} n , has been synthesized by the solvothermal reaction of Cd(CH3COO)2·2H2O with the synthesized ligand (S)-2-(benzylamino)succinic acid (H2 L). The title compound has been structurally characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction analysis. In the crystal structure, each CdII cation binds to three carboxylate groups from three symmetry-related L 2− dianions. The tetradentate L 2− ligand links three symmetry-related CdII cations into a 2D folding sheet, which can be simplified as a uninodal (3,3)-connected hcb net with the point symbol (63). In the lattice, all the folding sheets are arranged in an interdigitated fashion and aggregate into zipper-like arrays through interlayer π–π interactions. The large and nonpolar side chain may play an important role in the formation and aggregation of the 2D sheet. The thermal stability and photoluminescence properties of the title compound were investigated, and it exhibits a blue emission with a quantum yield of 8%.

AbstractA new two-dimensional ZnII coordination framework [Zn(1,3-BMIB) (OBA)]n (1) (where H2OBA is 4,4ʹ-oxy-bis(benzoic acid) and 1,3-BMIB is 1,3-bis(2-methyl-1-imidazolyl)benzene) has been prepared and characterized through IR spectroscopy, elemental and thermal analysis, and single-crystal X-ray diffraction. Complex 1 is a (4, 4) grid coordination polymer with a layer structure. It exhibits high photocatalytic degradation effects upon UV irradiation of methylene blue and methylene orange aqueous solutions.

A novel two-dimensional CdII coordination framework, poly[[[μ-1,3-bis(2-methyl-1H-imidazol-1-yl)benzene-κ2 N:N′](μ-1,3-phenylenediacetato-κ4 O,O′:O′′,O′′′)cadmium(II)] dihydrate], {[Cd(C10H8O4)(C14H14N4)]·2H2O} n or {[Cd(PDA)(1,3-BMIB)]·2H2O} n [1,3-BMIB is 1,3-bis(2-methyl-1H-imidazol-1-yl)benzene and H2PDA is 1,3-phenylenediacetic acid], has been prepared and characterized using IR, elemental analysis, thermal analysis and single-crystal X-ray diffraction, the latter revealing that the compound is a (4,4) grid coordination polymer with layers oriented parallel to the bc crystal planes. In the crystal, adjacent layers are further connected by O—H...O and C—H...O hydrogen bonds, forming a three-dimensional structure in the solid state. In addition, the compound exhibits strong fluorescence emissions and shows photocatalytic activity for the degradation of methylene blue in the solid state at room temperature.
