Indolocarbazole derivatives have been reported to be promising organic semicon- ductor candidates and electroluminescent (EL) materials. One novel indolocarbazole derivative, 2,8-acetyl-5,11-dihexyl-6,12-(di-p-tolyl)-5,11-indolo[3,2-b]carbazole (YK4), has been synthesized, and its crystal structure has also been carefully studied. YK4 is triclinic, space groups Pi with a = 9.409(5), b = 13.974(5), c = 15.488(5) A, α = 90.281(5), β = 105.456(5), Z= 93.728(5)°, M,. = 688.94, V= 1958.1(14) A3, Z = 2, Dc.= 1.168 g/cm-3,μ = 0.070 mm-1, F(000) = 740, Rint = 0.0475, R (I〉 20(/)) = 0.1146, wR (I〉 20(/)) = 0.2186, R(all data) = 0.2192 and wR (all data) = 0.2701. Like other indolo[3, 2-b]carbazole derivatives which were introduced in the 5- and 11-positions, the intermolecular short contacts are localized between the pendant groups and acetyl groups of the neighboring indolocarbazole molecules. The molecule of YK4 possesses poor face-to-face π-π stacking between two adjacent molecules in the crystal. The calculated bond lengths and bond angles of YK4 also proved the result of crystallography.  相似文献

A new 4,5-diaryl-lH-imidazole was synthesized and characterized by 1H NMR, ESI-MS, elemental analysis and FT-IR. The crystal structure of the title compound (C19H16C12N202, Mr = 375.24) has been determined by single-crystal X-ray diffraction. Crystal parameters: mono- clinic system, space group P2/n, a = 14.349(3), b = 8.7918(18), c = 15.352(3) A, β = 108.56(3)°, V = 1836.1(6) A3, Z = 4, F(000) = 776, Dc = 1.357 g/cm3, p = 0.368 mm-1, the final R = 0.0502 and wR = 0.1066 for 2324 observed reflections with 1 〉 2 σ(/). A total of 16117 reflections were collected, of which 3615 were independent (Rint = 0.0595). The preliminary bioassay suggested that the title compound exhibits distinct effective inhibition on the proliferation of cancer cell lines.  相似文献

The first part of this report describes the data reduction of non-merohedrally twinned crystals measured on Bruker and Agilent area-detector diffractometers. The image frames of methyl-2-aminopyrazine-3-carboxylate were processed with APEX2 to furnish a set of overlapping diffraction indices that were used for solution and refinement. CrysAlisPRO was used for processing the frames of bis(diethyldicarbamato)nickel, which exists in monoclinic and tetragonal polymorphs, and in untwinned and twinned forms. In the second part, the crystal structure of [(3-formyl-4- hydroxyphenyl)methyl]triphenylphosphanium chloride was refined through the ‘HKLF 5'(based on a combined set of diffraction indices) and PLATON(based on one set of diffraction indices) routes to give identical outcomes because the amount of overlap of the twin domains is small. For the third part, in a proof-of-concept investigation, the diffraction pattern of untwinned and twinned 4-{(E)-(4-aminophenyl)diazenyl]phenylamine was recorded simultaneously in one run; the three domains could be indexed and the crystal structure satisfactorily refined. The refinement was identical to those derived from independent measurements; the crystal structure features two independent centrosymmetric molecules, one of which is ordered and the other whole-molecule-disordered. This two-in-one run opens up the possibility that two or more crystals having different atomic compositions can be measured simultaneously if their reciprocal lattices do not overlap significantly.  相似文献

A new coordination polymer, namely [Ca(HOABDC)]n(1, H3 OABDC = 5-oxyacetateisophthalic acid), has been synthesized through hydrothermal reactions of Ca(NO3)2 and H3 OABDC. The title compound crystallizes in monoclinic, space group P21/c with a = 4.3043(2), b = 21.4959(11), c = 10.7450(6) A, β = 91.411(5)o, V = 993.88(9)A3, C10H6O7 Ca, Mr = 278.23, Z = 4, Dc = 1.859 g/cm3, F(000) = 560, μ = 0.659 mm-1, the final R = 0.0328 and wR = 0.0670 for 1469 observed reflections(I 2A(I)). Single-crystal X-ray structural analysis reveals that compound 1 features 1D Ca(Ⅱ)-carboxylate chain-shaped subunits, which are further connected together via HOABDC2- ligands into a 3D(6,6)-connected nia-type hybrid framework. Moreover, the luminescent property and thermal stability of 1 were also investigated.  相似文献

The compound was characterized by single-crystal X-ray diffraction. It crystallizes in triclinic, space group Pī with α = 11.650(2), b = 12.240(2), c = 19.760(4) A, α = 72.01(3), β = 77.11(3), γ = 83.48(3)°, V = 2609.4(9) A3, Z = 2, C56H31Cd3Cl2F2N8O14.25, Mr = 1489.99, Dc = 1.896 g/cm3, F(000) = 1466, μ(MoKa) = 1.401 mm^-1, R = 0.0401 and wR = 0.1104. Compound 1 shows a 1D chain structure, and the neigh- boring 1D chains of 1 are joined together by π···π interactions to result in a 2D supramolecular layer. In addition, the luminescent property of 1 has been studied in the solid state at room temperature.  相似文献

A novel two-dimensional Mn(II) coordination polymer, [Mn3(L)R(cis-chdc)fftrans- chdc)]n (L = 2-amino-4-(1H-imidazo[4,5-J][1,10]phenanthrolin-2-yl)phenol and chdc = 1,4-cyclo- hexanedicarboxylate), has been hydrothermally synthesized and characterized by elemental analysis, IR, TG PL and single-crystal X-ray diffraction. Crystallographic data for this compound: monoclinic space group P2/n with a = 11.0058(13), b = 9.0179(11), c = 28.431(3) A, β = 92.850(2)°, V = 2818.3(6) A3, Z = 2, C62Hs6Mn3N10O14, Mr = 1329.99, Dc = 1.567 g/cm3, F(000) = 1370, p(MoKa) = 0.742 mm-1, R = 0.0553 and wR = 0.1421. The chdc carboxylates bridge the Mn(II) atoms to form a trinuclear Mn(lI) cluster. The cis-chdc ligands are held together by the trinuclear Mn(II) clusters to result in a chain structure. Further, the trans-chdc ligands link adjacent chains to furnish a two-dimensional network. The π-π interactions between neighboring layers link the adjacent layers into a three-dimensional supramolecular architecture. Moreover, the N-H...O and O-H...O hydrogen bonds further stabilize the 3D supramolecular architecture.  相似文献

The coordination polymer, [Mn3(bpta)2(bip)2], (H3bpta = biphenyl-3,3',5-tricar- boxylic acid, bip = 2,6-bis(imidazole-1-yl)pyridine), has been synthesized under hydrothermal con- ditions and characterized by elemental analysis, FT-IR, XRD, TGA and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 14.919(3), b = 9.780(2), c = 20.352(7) A, V = 2344.4(10) A3, Z= 2, C52H32Mn3N10012, Mr = 1153.70, Dc = 1.634 g/cm3, p(MoKa) = 0.876 mm-1, F(000) = 1170, the finalR = 0.0605 and wR = 0.1177. The complex forms a 2D layer with trinuclear Mn(II) units and further assembles into a 3D supramolecular network structure through C-H..'O hydrogen bonding and C-H...π interactions. Moreover, the negative J value indicates the presence of antiferromagnetic coupling between the Mn(II) ions within a trinuclear unit.  相似文献

Hydrothermal reactions of three aromatic polycarboxylic acids and the transitional metal cations in the presence of phen and 1,4-bib afford three new coordination polymers: [Cd2(bpp)1.5(Hbpp)(phen)2]n (1), [Mn3(Htptc)2(phen)2(H2O)2]n (2), and {[Cu(btc)0.5(1,4- bib)]·2H2O}n(3) (H2bpp = 2,6-bis(4'-carboxyphenyl)-4-phenylpyridine, H4tptc = terphenyl-2,5,2',5'-tetracar- boxylic acid, H4btc =biphenyl-2,2',4,4'-tetracarboxylic acid, phen =1,10-phenanthroline, and 1,4-bib = 1,4-bis(1H-imidazol-1-yl)benzene). Their structures have been determined by single- crystal X-ray diffraction analyses, elemental analyses, IR spectra, and powder X-ray diffraction (PXRD) analyses. In compound 1, the CdII cations are linked by bpp2- to form one ladder structure, based on which a 3D network is constructed with the help of non-covalent interactions. The topology of 2 is a 3D (3,4,5)-connected framework with the Point Schl?fli symbol of (42.6)2(43.62.8)(45.64.8)2. Compound 3 shows an unprecedented 3D (4,4)-connected framework with the Point Schl?fli symbol of (64.82)2(65.8). Moreover, the luminescent property of 1 has been investigated.  相似文献

A new cadmium-organic framework, [Cd2(TBDC)2(DMF)2(H2O)]n (1), was synthesized by solvothermal reaction of rigid carboxylate ligand 2,3,5,6-tetramethyl-l,4-ben- zenedicarboxylate (H2TBDC) and cadmium nitrate and characterized by elemental analysis, infrared spectrum, thermal analysis, PXRD, single-crystal X-ray diffraction and photoluminescence in the solid state. Compound 1 crystallizes in orthorhombic, space group Pca21 with a = 21.487(6), b = 7.790(2), c = 20.666(6) A, C30H40Cd2N2O11, Mr = 829.44, V= 3459.3(16) A3, Z = 4, Dc = 1.593 g.cm-3,μ = 1.29 mm-1, F(000) = 1672, 2.7〈θ〈27.2°, λ(MoKa) = 0.71073 A, T= 293(2) K, the final R = 0.026, wR = 0.0548 and S = 1.027. X-ray diffraction analysis reveals that complex 1 possesses a 3D framework and exhibits rnsw net. Thus, the solid-state luminescent spectrum of 1 displays that the emission of cadmium(lI) complex shows a peak at 317 nm upon 250 nm excitation at room temperature.  相似文献

The Ni atoms in 1 or 2 are chelated by two dmpzm ligands and one formate or acetate anion, forming slightly distorted octahedral geometries. In the crystals of 1 or 2, intermolecular hydrogen bonding interactions result in the formation of 2D hydrogen-bonded frameworks.  相似文献

A three-dimensional(3D) barium complex with 1,3,5-benzenetricarboxylic acid(H3BTC), {[Ba1.5(BTC)(H2O)]·(H2O)}n(1), was synthesized in DMF/EtOH/H2 O mixed solution under solvothermal conditions, and characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, thermogravimetric analyses, and photoluminescence measurement. In complex 1, the 2D I2O0 type inorganic layer is constructed by {Ba1O10} and {Ba2O9} polyhedra. Moreover, the solid-state fluorescence measurement reveals a fluorescence emission band at 465 nm under 344 nm excitation, assigned to a charge-transfer transition.  相似文献

Hydrothermal reactions of two imidazole derivatives(1,3,5-tib = 1,3,5-tris(1Himidazol-1-yl)benzene, 1,4-bimb = 1,4-bis(1H-imidazol-1-ylmethyl)benzene) and the ZnⅡ cations in the presence of oxalic acid(H2ox) afford two coordination polymers, namely, {[Zn(ox)(1,3,5-tib)]·2(H2O)}n(1) and [Zn1.5(ox)1.5(1,4-bimb)1.5]n(2). Their structures have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, and powder X-ray diffraction(PXRD) analyses. Both complexes 1 and 2 are based on the 1D zigzag [Zn(ox)]n chains, and their final structures are controlled by the two different imidazole linkers, which expanded the structure along different directions, finally giving a 3D dia net for 1 and a 2D sql layer for 2. Moreover, the luminescent properties of 1 and 2 have been investigated.  相似文献
