5 [HL = 4-chlorophenyloxyacetic acid] have been synthesized and characterized by IR method, elemental analysis, X-ray powder diffraction (XRPD) analysis, fluorescence spectroscopy method, and single-crystal X-ray diffraction techniques. X-ray structure analysis reveals that complex 1 is 1D chain polymer, complex 5 is 2D network polymer, while complex 2, 3, and 4 are all 0D structure. The L ligand have many kinds of coordination mode, which make these complexes have different configuration. The weak C-H···O and π -π interactions are also very important, the mononuclear or multinuclear crystal units of these complexes can be packed through them. Moreover, all these complexes exhibit fluorescence.
Assembly of 4,4'-oxybis(benzoic acid) (H2L) with manganese chloride in the presence of 2,2'-biphenyl (2,2'-bpy) affords a new coordination polymer [Mn3L3(2,2'-bpy)2]n (1), in which the [MnL2]n layers are extended by L bridges resulting in a three-dimensional (3-D) coordination framework. The network structure of 1 has unusual (2,6)-connectivity and represents a new type of (812·123)(8)(3) topology. These identical and complementary networks are entangled to generate a self-penetrating supramolecular lattice. Moreover, the fluorescence spectrum of 1 exhibits fluorescent emission in the solution of methanol at room temperature. Electrochemical investigation illustrates the electrochemical properties of the title compound.

Source of materialBenzenetricarboxylic acid (H 3 BTC, 0.105g,0.5 mmol)was dissolved in themixture of 5mlcarbinol and 15 ml H 2 O. Then an aqueous solution of sodium hydroxide was added dropwise with stirring to adjust the pH value of the solution to 5. At last, 10 ml aqueous solution of Zn(CH 3 COO) 2 × 4H 2 O(0.1090 g, 0.5mmol) was put in. The mixture was kept stirring for 5hat75°Cand then filtered.The filtrate was kept at room temperature and three days later, X-ray quality colorless block-shaped single crystals were obtained. Thec rystals were isolated, washed withc arbinol and driedatroomtemperature(yield 65 %based on Zn). Elemental analysis -found: C, 27.60 %, H, 2.80 %; calculated for C 18 H 22 Na 2 O 23 Zn 2 :C,27.62 %, H, 2.81 %. IR data areavailabeinthe CIF file.
In the title complex, [CuCl2(C10H7N3S)(C2H5OH)], the CuII ion is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a 2-(1,3-thiazol-4-yl)-1H-benzimidazole ligand, one O atom from an ethanol molecule and two Cl atoms. In the crystal, O—H⋯Cl and N—H⋯Cl hydrogen bonds link the complex molecules into a layer parallel to (100). π–π interactions between the thiazole rings are observed [centroid–centroid distance = 3.749 (3) Å].
In the title complex, [Cd2(C17H14O4S)2(C10H8N2)2], which was hydrothermally synthesized, the CdII cation is hexacoordinated in a distorted octahedral geometry by two N atoms from a 2,2′-bipyridine ligand and by four O atoms from two different 2-[3-carboxylatomethyl-4-(phenylsulfanyl)phenyl]propanoate ligands, forming a cyclic dimetallic complex.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
