One transition metal-organic framework [Zn(TBTC)(2,6-pydc)]n (1), has been assembled from a mixed ligand 4,5,9,14-tetraaza-benzo[b] triphenylene-11-carboxylic acid (HTBTC) with the help of pyridine-2,6- dicarboxylic acid (2,6-pydc)ligand. X-ray single crystal diffraction analysis reveals that compound 1 crystallizes in the space group of P21/c and displays a one-dimensional (1D) zigzag infinite chain, which is extended via the π-π stacking interactions between pyrazine rings and benzene rings to form 2D supramolecular layers. Compound 1 shows an excellent photocatalytic activity through degradation of methyl blue (MB), methyl violet (MV), rhodamine B (RhB) and orange G (OG). The rate of photodegradation for MV can reach 90% under Xe lamp irradiation after 4.5 h. In addition, catalytic mechanism was also discussed. © 2014 Elsevier B.V. Source

One metal-organic framework, [Co2(1,4-BDC)(NCP) 2]n·4nH2O (1) (1,4-H2BDC denotes benzene-1,4-dicarboxylic acid, HNCP denotes 2-(4-carboxyphenyl) imidazo(4,5-f)(1,10)phenanthroline), has been hydrothermally synthesized and characterized via single crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis and diffuse-reflectance UV-vis spectrum study. Compound 1 shows a 2D layer structure, which is further extended into a 3D supramolecular network structure through π-π stacking interactions. The photocatalytic study on compound 1 indicates that it is an active catalyst for the degradation of orange G, rhodamine B, methylene blue and methyl violet. © 2013 The Authors. Source

Ten coordination polymers, namely, [Cu(HL)2] (1), [Cu(HL) 2]·2DMA (2) [Co2(L2)(DMF)]·DMF (3), [Co(L)(H2O)2]·DMF (4), [Co5(L) 4(OH)2(H2O)2]·4DMF (5), [Cd(L)(DMF)] (6), [Cd(L)(DMA)] (7), [Cd2(L)2(H 2O)4]·3H2O (8), [Mn2(L) 2(H2O)4]·3H2O (9) and [Mn(L)(DMF)2] (10), have been synthesized in mixed solvents under solvothermal conditions. Compound 1 reveals a one-dimensional (1D) chain, which is extended by hydrogen bonding interactions to generate a supramolecular layer. Compound 2 also shows a 1D chain, which is further linked by π-π and hydrogen bonding interactions to form a 3D supramolecular architecture. Compound 3 features a 3D (3,6)-connected net with (42·6)(4 4·62·88·10) topology. Compound 4 displays a 2D (3,4)-connected network with (4·6 2)(42·62·82) topology. These layers are linked by hydrogen bonds to form a 3D supramolecular framework. Compound 5 furnishes a 3D binodal (3,12)-connected net with (4 3)2(420·628·8 18) topology. Compound 6 possesses a 4-connected layer with (4 3·63) topology. Compound 7 reveals a 3D 4-connected framework with 4·65 topology. Compounds 8 and 9 are isostructural and exhibit similar 2D 63-hcb nets, which are further extended by hydrogen-bonding interactions into 3D supramolecular architectures. Compound 10 possesses a 2D 3-connected fes network. These complexes were characterized using X-ray single-crystal diffraction, elemental analysis, IR spectroscopy, PXRD and TGA. Moreover, the diffuse reflectivity spectra and the solid state photoluminescent properties of the ligand and compounds have also been studied at room temperature.

In this article, four new lead(II) coordination polymers based on a N,O-donor ligand 2′-(1 H-1,3,7,8-tetraaza-cyclopenta[l]phenanthren-2-yl) biphenyl-2-carboxylic acid (HL) have been hydrothermally synthesized, namely, [PbL2]·2H2O (1), [PbL2]·2H 2O·CH3CH2OH (2), [Pb5L 2(m-BDC)4]·3H2O (3) and [Pb 2L2(p-BDC)] (4), where m-BDC = 1,3-benzenedicarboxylate and p-BDC = 1,4-benzenedicarboxylate. Compound 1 shows a 2D bilayer structure, which is further extended into a 3D supramolecular structure through π-π stacking interactions. Compound 2 shows a 3D supramolecular structure based on a zero-dimensional molecule by π-π stacking interactions of neighboring molecules. Compound 3 shows a 2D layer structure. Compound 4 displays a 1D chain-like structure, which is then stacked by π-π interactions to result in a 2D supramolecular structure. Solid-state luminescent spectra of four lead(II) complexes indicate intense fluorescent emissions. © 2012 Elsevier B.V. All rights reserved. Source

Five new coordination polymers, namely [Co2(bbi) 2(SO4)2] (1), [Zn2(IA) 2(bbi)2] (2), [Cd(AIP)(bbi)0.5]·H 2O (3), [Zn(PDC)(bbi)] (4) and [Cd(PDC)(bbi)]·2H2O (5) (H2IA = itaconic acid, H2AIP = 5-aminoisophthalic acid, H2PDC = pyridine-2,3-dicarboxylic acid and bbi = 1,4-bis(1H-imidazol-1-yl)butane, have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. The X-ray crystallographic studies of 1 and 5 reveal 3D threefold interpenetrating diamondoid architectures. Compound 2 displays a diamondoid topology. Compound 3 shows a 3D five-connected (42·68) net. Compound 4 displays an undulating layer structure, where the layers are further stacked by π-π interactions to generate a 3D supramolecular architecture. The photoluminescent behaviors of 2-5 have also been investigated. © 2013 Elsevier Ltd. All rights reserved. Source
