“…However, 4-nitro-thiophene-2-carboxylic acid involving in situ decarboxylation of 3-nitro-thiophene-2,5-dicarboxylic acid has been obtained at higher reaction temperature. However, there have been reports of decarboxylation reactions mediated by metal ions under hydro(solvo)-thermal conditions [8,9], the transformation of 4-nitro-thiophene-2-carboxylic acid using a simple in situ thermal decarboxylation of 3-nitro-thiophene-2,5-dicarboxylic acid in aqueous solution is straightforward and applicable. Presented herein is the crystal struture of 4-nitro-thiophene-2-carboxylic acid.…”

CCDC no.: 1445929The asymmetric unit of the crystal structure is shown in the gure. Tables 1-3 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialA mixture of the 3-nitro-thiophene-2,5-dicarboxylic acid (21.7 mg, 0.1 mmol) and 10 mL distilled water in a 25 mL Te on-lined autoclave was kept under autogenous pressure at 413 K for 1 days. After cooling to room temperature at a rate of 5K h −1 , light yellow block crystals were collected by ltration and washed with distilled water in 76% yield.

Under hydrothermal conditions, three new Ag I coordination polymers, [Ag(L1)(Hmip)] n (1), [Ag(L2) 0.5 (ndc) 0.5 ] n (2), and {[Ag(L3) 0.5 (Htbi)]·0.25H 2 O} n (3) [H 2 mip = 5-methylisophthalic acid, L1 = 1,4-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H 2 ndc = 2,6naphthalenedicarboxylic acid, L2 = 1,3-bis(2-methylbenzimidazol-1ylmethyl)benzene, H 2 tbi = 5-tert-butyl isophthalic acid, L3 = 1,4bis(5,6-dimethylbenzimidazole)butane] were synthesized by employing flexible bis(benzimidazole) and dicarboxylic acid ligands. Polymer 1 displays a 2D 4-connected 4L2 underlying net topology with the point symbol of (6 5 .8) in standard representation. Compound 903 2 possesses a 2D uninodal 4-connected Shubnikov tetragonal plane net (sql) based on a dinuclear Ag I clusters with the point symbol (4 4 .6 2 ), which is further extended into a 3D supramolecular framework by ππ interactions. Compound 3 possesses dinuclear molecular complex groups, which form chains by weak Ag-O (2.6 Å) coordination bonds, and further assembled into a 2D supramolecular layer by hydrogen bonds and π-π stacking interactions. These complexes exhibit intense fluorescent emissions in solid state. UV/Vis diffuse reflection spectra and the excellent catalytic activity for the degradation of the congo red azo dye in a Fenton-like process are discussed. 904 and H 2 mip.

ConclusionsThree new metal-organic coordination complexes were successfully synthesized under hydrothermal condition. Topological analysis reveals that complex 1 is a new representative in rare isoreticular series of 2D 4-connected networks with 4L2 topology, which is constructed from four-coordinate Ag I ions and bridging bidentate ligands. Polymer 2 forms a 3,4-coordinated net with 3,4L13 topology in standard representation and a uninodal 4-connected net with widespread sql topology in cluster representation, which is further extended into a 3D supramolecular framework by the interlayer π-π stacking. Complex 3 shows a dinuclear structure, and a 2D supramolecular network was obtained by hydrogen bonding and π-π interactions. The variation of the organic ligand plays an important role in the construction of these complexes. 1-3 exhibit strong emission in the solid-state at room temperature. Moreover, 1-3 show promising catalytic activities in the Fenton-like decomposition of congo red.
