The complex [Cu( μ3-I)INH]n has been synthesized in DMF solution with INH, CuI, where INH=isoniazid. The crystal structure of the complex has been determined by X-ray diffraction single crystal structure analysis. The crystal belong to monoclinic system, space group P21/c. The cell parameters are: a=1.009 48(10) nm, b=0.467 51(5) nm, c=1.992 62(19) nm, β=101.413 0(10)°, and V= 0.921 81(16) nm3, Z=4, μ(Mo Kα)=5.674 mm-1, F(000)=616.0, R1=0.031 6, wR2=0.082 5 [I2σ(I)]. The copper(Ⅰ) atom locates in a distorted coordination tetrahedron. The copper(Ⅰ) atoms bridged by μ3-I to form a band stair-like chain, and INH occupying the remaining coordination site of the approximately tetrahedral. The stair-like chains extend along b axis. The results of TG analysis show the title complex was stable under 200℃. 相似文献

以醋酸锌、异烟肼(INH)、2-氨基吡啶(2-APy)为原料在N,N-二甲基甲酰胺(DMF)溶液中合成了2个Zn(Ⅱ)配位聚合物[Zn(CH3COO)2(INH)]n(1),[Zn(CH3COO)2(2-APy)]n(2),用红外光谱、元素分析、粉末X射线衍射、X射线单晶衍射对配合物进行了表征。晶体结构测试表明,配聚物1属单斜晶系,空间群P21/c,晶胞参数:a=0.914 44(17)nm,b=0.161 86(3)nm,c=0.871 75(16)nm,β=96.181(3)°,V=1.282 8(4)nm3,Z=4;配聚物为2D层状结构,该层状结构通过氢键弱相互作用,进一步形成3D超分子结构。配聚物2属三斜晶系,空间群P1,晶胞参数:a=0.747 0(4)nm,b=0.814 5(5)nm,c=1.895 7(11)nm,α=88.276(8)°,β=86.202(8)°,γ=84.334(8)°,V=1.144 9(11)nm3,Z=2;配聚物2为一维zig-zag链状结构。室温固态荧光测试显示,配聚物1、2分别在最大波长382.6和367.5 nm处具有较强的荧光发射。 相似文献

Two new Schiff bases based on 5-chloro-3-methyl-1-phenyl-1 H-pyrazole-4-carbaldehyde, namely, N-((5-chloro-3-methyl-1-phenyl-1 H-pyrazol-4-yl)methylene)-4-morpholinoaniline(Ⅲa) and N-((5-chloro-3-methyl-1-phenyl-1 H-pyrazol-4-yl)methylene)-3-fluoro-4-morpholinoaniline(Ⅲb), were synthesized and characterized by IR, LC-MS, 1 H NMR and 13 C NMR spectroscopy. Meanwhile, the three-dimensional configurations of the two title compounds were further characterized by single-crystal X-ray diffraction analyses. Both the compounds are thermodynamically stable trans-isomers. Moreover, the fluorescence properties and antioxidant activities against DPPH of the two target compounds have been investigated, and the results showed that the title compounds both have fluorescence performance and certain antioxidant activities against DPPH radical. 相似文献

以碘化汞为原料,分别与3,5-二(4-吡啶基)-1,2,4-三唑(L1),4-氨基-3,5-二(4-吡啶基)-1,2,4-三唑(L1)在N,N-二甲基甲酰胺(DMF)溶液中反应,合成了2个一维链状Hg(Ⅱ)配聚物{[Hg2I4(4-bpt)2]·3DMF}n(1),{[Hg2I4(L2)]·DMF}n(2)。用红外光谱、元素分析、X-射线单晶衍射对配合物进行了表征。X-射线单晶衍射表明,配聚物1中汞离子位于扭曲的配位四面体中心,相邻汞离子通过分别与L1的3个端基N原子配位,桥连形成了一维zig-zag链结构,碘离子占据配位四面体的剩余两配位点,配聚物1的一维链平行于bc平面。配合物2中汞离子位于扭曲的配位四面体中心,分别与L2的一个吡啶N原子和3个碘离子配位,其中2个碘离子充当桥联配体将相邻汞离子连接,形成了一维-Hg-I-Hg-I-的zig-zag链,相邻的-Hg-I-Hg-I-链进一步通过作为双齿配体的L2连接,形成一独特的一维双链梯状聚合物,配聚物2一维链平行于a方向。室温固态荧光测试显示,配聚物1在383.7nm处具有强的荧光发射,而配聚物2在299.7nm和376.5nm处具有强的荧光发射。 相似文献
