Two new metal-organic complexes,{[Co2(bptc)(DPPZ)2(H2O)2]·H2O}n 1 and {[Co2(ccm)2(DPPZ)2]·2H2O}n 2,were obtained by the hydrothermal reactions of Co(NO3)2·6H2O with chelating ligand dipyrido[3,2-a:2',3'-c]phenazine(DPPZ) and the corresponding carboxylic acid,namely,3,3',4,4'-benzophenonetetracarboxylic acid(H4bptc) or 2-carboxycinnamic acid(H2ccm),respectively.The complexes were structurally characterized by single-crystal X-ray diffraction,elemental analyses,IR spectra,and thermal gravimetry.1 presents unique chiral chain structures,which are further consolidated into three-dimensional supramolecular frameworks via noncovalent bonds,such as hydrogen bonding and π-π interactions.2 features infinite double-chain structures,which are connected by strong π-π interactions to result in three-dimensional supramolecular architectures. 展开更多

A binuclear zinc(Ⅱ) complex with 2-carboxycinnamic acid (2-ccm) and dipyrido- [3,2-a:2',3'-c]phenazine (DPPZ), {[Zn2(2-ccm)2(DPPZ)2]·2H2O}n, was synthesized and characterized by elemental analysis, IR, single-crystal X-ray diffraction, thermal gravimetry and fluo- rescent emission. It crystallizes in monoclinic, space group P21/c with a = 13.409(4), b = 25.530(7), c = 13.952(4) A, β = 99.554(3)°, V= 4710(2) A3, Z= 4, C56H36N8O10Zn2, Mr= 1111.67, Dc = 1.568 g/cm3, μ(MoKα) = 1.093 mm^-1, F(000) = 2272, R = 0.0422 and wR = 0.0895. In the crystal, the basic unit of 1 is a binuclear Zn2 entity which is linked by 2-ccm ligand to form a 1D double chain along the a axis. The O-H...O hydrogen bonding and π-π interactions lead to a 3D supramolecular motif. In addition, thermal and luminescent properties of complex 1 have also been investigated. 展开更多

ABSTRAC Two new complexes [Cd(2,4'-bpdc)(DPPZ)]2n·n H2O(1) and [Zn(2,4'-Hbpdc)2(DPPZ)]· H2O(DPPZ = dipyrido[3,2-a:2',3'-c]phenazine, 2,4'-H2bpdc = 2,4'-biphenyldicarboxylic acid) have been hydrothermally synthesized. The structure of complex 1 was determined by single-crystal X-ray diffraction diffraction and further characterized by elemental analysis, IR spectrum, powder X-ray diffraction(XRD) and single-crystal X-ray diffraction. Complex 1 has 1D chains, which are further connected by π-π stacking interactions of neighbouring chains, generating a steady 3D supramolecular structure. Complex 2 shows the isolated mononuclear units, which are further extended to a 2D supramolecular layered structure through π-π stacking interactions and hydrogen bonds. Furthermore, complexes 1 and 2 exhibit green photoluminescent properties at room temperature. 展开更多

In this work,a new two-dimensional Cd(Ⅱ) coordination polymer,[Cd3(L)2(cis-1,4-chdc)2(trans-1,4-chdc)](1,L = 11-fluoro-dipyrido[3,2-a:2’,3‘-c]phenazine and 1,4-H2 chdc = 1,4-cyclohexanedicarboxylatic acid),has been prepared under hydrothermal conditions.It crystallizes in triclinic,space group P1 with a = 8.6951(8),b = 10.8362(9),c = 14.9445(13) A,α = 76.443(2),β = 81.8670(10),γ = 82.0640(10)°,V = 1347.0(2) A^3,Z = 1,C60H48Cd3F2N8O12,Mr = 1448.26,Dc = 1.785 g/cm^3,F(000) = 722,μ(Mo Ka) = 1.255 mm^-1,R = 0.0333 and w R = 0.0790.The 1,4-chdc^2-carboxylates bridge the Cd(Ⅱ) cations to form a tri-nuclear Cd(Ⅱ) cluster,which are held together by the cis-1,4-chdc^2-ligands to generate a double-stranded chain.Further,the trans-1,4-chdc^2-ligands bridge adjacent double-stranded chains to yield an interesting two-dimensional network.The π-π interactions among L ligands of neighboring networks result in an interesting three-dimensional supramolecular architecture.In addition,the thermal behavior and luminescent property of 1 have been studied. 展开更多

A new two-dimensional Pb(Ⅱ) coordination polymer, [Pb2(L)(tpphz)1.5(NO3)2]·H2O(1), has been obtained by the hydrothermal reaction of tetrapyrido[3,2-a:2′,3′-c:3′′,2′′-h:2′′′,3′′′-j]-phenazine(tpphz) and 2,2′-bipyridyl-3,3′-dicarboxylic acid(H2L). It crystallizes in monoclinic, space group P21/c with a = 15.344(3), b = 14.111(3), c = 21.963(4) ?, β = 106.89(3)o, V = 4550.1(16) ?3, Z = 4, C48H26N13O11Pb2, Mr = 1375.20, Dc = 2.007 g/cm^3, F(000) = 2628, μ(Mo Ka) = 7.471 mm-1, R = 0.0339 and w R = 0.0808. In 1, the two crystallographically independent tpphz ligands adopt the same bis-chelating coordination mode, but they play different roles in the structure of 1. One type of tpphz ligands bridge the Pb(Ⅱ) cations to generate a zigzig chain, where the L anions are located on one side of the chain. Further, adjacent chains are linked by the other type of tpphz ligands into a two-dimensional layer structure. Additionally, the solid state luminescent property of 1 was also studied at room temperature. 展开更多

A new porous Cd(Ⅱ) coordination compound, namely, [Cd(bpdc)(L)2]·3H2O(1, L = 11-fluoro-dipyrido[3,2-a:2,3-c]phenazine and bpdc = 1,1-biphenyl-2,2-dicarboxylate) was synthesized under hydrothermal conditions, and characterized by single-crystal X-ray diffraction. It crystallizes in tetragonal, space group P4122 with a = 9.8486(4), b = 9.8486(4), c = 45.925(4)A, V = 4454.5(5) 3, Z = 4, C50H29 Cd F2N8O7, Mr = 1004.21, Dc = 1.497 g/cm^3, F(000) = 2028, μ(Mo Ka) = 0.562 mm^-1, R = 0.0566 and w R = 0.1585. Each Cd(Ⅱ) atom is coordinated by one bpdc anion and two L ligands to give a discrete molecule. Neighboring discrete molecules are stacked by π-π interactions among L ligands, resulting in an interesting 1D supramolecular chain. Moreover, the 1D supramolecular chains are packed with each other to give a porous structure, in which an infinite channel is filled with water molecules. In addition, the thermal behavior and luminescent property of 1 have also been studied. 展开更多
