The crystal structure of the title compound 1-(4-fluorophenyl) -2-hexylthio-benzo [4,5]furo[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidin-5(1H) -one(C23H21FN4O2S,Mr = 436.5) has been prepared and determined by single-cr... The crystal structure of the title compound 1-(4-fluorophenyl) -2-hexylthio-benzo [4,5]furo[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidin-5(1H) -one(C23H21FN4O2S,Mr = 436.5) has been prepared and determined by single-crystal X-ray diffraction. The crystal is of monoclinic,space group P21/n with a = 13.9854(3) ,b = 17.2678(4) ,c = 18.1828(5)A,β = 99.364(2) °,V = 4332.58(18) A^3,Z = 4,Dc = 1.338,F(000) =1824,μ = 0.185 mm^-1,MoKa radiation(λ = 0.71073) ,R = 0.0538 and wR = 0.1162 for 4728 observed reflections with I 〉 2σ(I) . X-ray diffraction analysis reveals the fused rings of benzo[4,5]furo[3,2-d]-1,2,4-triazolo[1,5-a] pyrimidin-5(1H) -one system are nearly coplanar. The crystal packing is mainly stabilized by weak intermolecular C-H···O hydrogen bond and π-π interactions. 展开更多

A new one-dimensional Ni(Ⅱ) coordination polymer [Ni(L)(cis-1,4- chdc)]n·1.25nH2O has been synthesized under hydrothermal conditions by using 1,4-cyclohexanedicarboxylic acid (1,4-H2chdc) and 2-(3-fluor... A new one-dimensional Ni(Ⅱ) coordination polymer [Ni(L)(cis-1,4- chdc)]n·1.25nH2O has been synthesized under hydrothermal conditions by using 1,4-cyclohexanedicarboxylic acid (1,4-H2chdc) and 2-(3-fluorophenyl)- 1H-imidazo [4,5-f] [ 1,10]phenanthroline (L). Crystallographic data for the compound: triclinic, space group Pi with a = 8.777(2), b = 10.662(2), c = 13.799(3) A, a = 89.480(4), β = 73,933(3), γ = 81.980(4)°, V = 1228.2(5) A3, Z = 2, C27H22.50FN4NiO5.25, Mr = 568.70, Dc = 1.527 g/cm3, F(000) = 583,μ(MoKα) = 0.846 mm-1, R = 0.0634 and wR = 0.1465. Neighboring Ni(Ⅱ) atoms are linked by the cis-1,4-chdc ligands to generate a one-dimensional chain structure. The π-π interactions between the L ligands of neighboring chains led to the formation of a two-dimensional supramolecular layer. The elemental analysis, IR spectrum and TG of the compound have been studied. 展开更多
