Two inorganic-organic coordination polymers, [Cd(TBA)2]·3H2O (1) and [Cu(TBA)2]·2H2O (2) have been synthesized by reaction of the metal ions of Cd(II) and Cu(II) with the ligand HTBA [HTBA = 4- (1H-1, 2, 4-t... Two inorganic-organic coordination polymers, [Cd(TBA)2]·3H2O (1) and [Cu(TBA)2]·2H2O (2) have been synthesized by reaction of the metal ions of Cd(II) and Cu(II) with the ligand HTBA [HTBA = 4- (1H-1, 2, 4-triazol-1-yl)benzoic acid] under solvothermal condition. The compounds were characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, X-ray powder diffraction (XRPD), and thermo gravimetric analysis (TGA). The structural analyses reveal the two independent polymers exhibit different structures. Complex 1 exhibits a 3D framework with 1D channels, and complex 2 shows a 2-fold interpenetrating 3D diamond net. 展开更多

The title compound has been synthesized by the reaction of 1-bromo-3,3-dime- thyl- 1 - (1 H- 1,2,4-triazol- 1 -yl)butan-2-one with 1 -(2-fluorophenyl)thiourea, and its crystal struc- ture was determined by single-crystal X-ray diffraction. The crystal belongs to the orthorhombic system, space group Pbca with a = 15.2568(6), b = 12.1533(5), c = 16.7307(7) A, Z = 8, V = 3102.2(2) A3, Mr = 317.39, Dc = 1.359 g/cm3, S = 1.05, μ = 0.223 mm-1, F(000) = 1328, the final R = 0.034 and wR = 0.097 for 2590 observed reflections (I 〉 2σ(I)). X-ray crystal structure presents the intramolecular N-H…N hydrogen bond, which plays an important role in stabilizing the crystal structure. In addition, the preliminary biological test on the title compound shows good antitumor activity, with IC50 of 0.122 μmol/mL against the Hela cell line. 展开更多

The title compound, 4-(tert-butyl)-5-(1 H- 1,2,4-triazol- 1 -yl)-N-(2-hydroxy-3,5-diio- dinebenzyl)thiazol-2-amine, was synthesized via the reduction of 4-(tert-butyl)-5-(1H-l,2,4- triazol-l-yl)-N-benzylidene-thiazol-2-amine with NaBH4, and its crystal structure was determined by single-crystal X-ray diffraction. The compound crystallizes in monoclinic system, space group P21/c with a = 7.91944(19), b = 10.5250(3), c = 24.4985(6) A, Z = 4, V = 2041.66(9) A3, Mr = 599.22, Dc = 1,949 Mg/m3, S = 1.120, p = 3.203 mm-1, F(000) = 1152, the final R = 0.0283 and wR = 0.0592 for 3490 observed reflections (I 〉 2σ(I)). X-ray analysis displays that the crystal water takes part in three intermolecular hydrogen bonds of O(2)-H(2A)…O(1), O(2)-H(2B)…N(I) and N(5)-H(5)…O(2), and an octatomic ring R^(8) is formed via intramolecular hydrogen bond of O(I)-H(IA)…N(4). Furthermore, the I…I contacts are involved in stabilizing the overall three-dimensional network structure. The preliminary biological test shows the title compound has good antitumor activity with the IC50 value of 26 μM against the Hela cell line. 展开更多

A new complex[Zn(3,4-APT)2(H2 O)4]·8 H2 O(1,3,4-HAPT=4-(5-(pyridin-3-yl)-4 H-1,2,4-triazol-3-yl)benzoic acid)has been prepared and characterized by elemental analysis,X-ray single-crystal diffraction analysis,thermogravimetric analysis and infrared spectrum analysis.Theoretical calculation based on density functional theory(DFT)is also employed to explicate frontier orbitals of 3,4-HAPT.X-ray single-crystal diffraction analysis reveals that 1 belongs to the triclinic system,space group P1 with a=7.5123(3),b=8.6745(3),c=15.2074(6)Å,α=78.469(1),β=87.387(1),γ=65.448(1)°,V=882.42(6)Å,Z=1,D_(c)=1.528 g·cm^(–3),μ=0.780 mm^(–1),M_(r)=812.09,F(000)=424,the final R=0.0401 and wR=0.1136.Zn(II)ion is coordinated by two N atoms from two 3,4-HAPT as well as four O atoms from four coordinated water molecules,forming a 0D motif with distorted octahedral coordinated geometry.The adjacent 0 D units are linked into a 3 D supramolecular structure through hydrogen bonding interaction.In addition,complex 1 exhibits better antifungal activity against Colletotrichum gloeosporioides Penz than the ligand and metal salt by MIC,MBC tests and Kirby-Bauer disc diffusion method which exhibit potential application in the antifungal fields. 展开更多
