A Cu(Ⅱ) complex [Cu(L)1.5(OSO3)]·3H2O (1) [L=1,4-bis(imidazol-1-yl)benzene] was synthesized by reaction of ligand L with CuSO4·5H2O using solvothermal method and its structure was determined by X-ray crystal structure analysis. The structure indicates that the complex crystallizes in triclinic, space group P1 with a=0.948 8(2), b=1.078 5(2), c=1.108 4(2) nm, α=74.820(2), β=81.331(2), γ=72.638(2)°, V=1.041 5(3) nm3, Z=2, Dcalc=1.687 g·cm-3, F(000)=544, μ=1.205 cm-1, the final R=0.062 3 and wR=0.132 8. The Cu(Ⅱ) atom has distorted square-pyramidal environment with a N3O2 donor set. Each L ligand links two Cu(Ⅱ) atoms using its imidazole groups to form an infinite one-dimensional (1D) ladder-like chain, which further linked by SO42- to form a two-dimensional (2D) network structure. The 2D sheets are further connected by C-H…O hydrogen bonds to give a three-dimensional (3D) structure. CCDC: 650388. 相似文献

本文通过溶剂热法合成了三个基于4'-羧基-2,2':6',2"-三联吡啶(HL)的单核配合物,其分子式为[ML2]·4H2O(1,M=Zn(Ⅱ);2,M=Cu(Ⅱ);3,M=Fe(Ⅱ)),并分别对其进行了元素分析、波谱、单晶和粉末衍射表征。晶体结构测试结果表明3个配合物为异质同晶结构,都属于四方晶系的I42d空间群。配合物1~3都是1个二价金属离子和2个羧基未配位且去质子化的三齿螯合配体L配位形成的单核结构,通过分子间π-π堆积和氢键作用拓展成三维超分子网络结构。由于二价Zn离子的全充满d10配位构型,配合物1与其配体相比具有明显的室温固态蓝色荧光发射性质。 相似文献

A new binuclear copper(Ⅱ) complex containing fluoroquinolone ligand, [Cu2(cfc)2(bpy)2(pip)]·6H2O, was synthesized and its crystal structure was solved. The formula of the complex is C25H26ClCuFN4O6, and the crystal-lography data are as follows, triclinic, space group P1, a=6.874(2)?, b=10.761(3)?, c=17.976(5)?, α=80.071(6)°, β=85.253(6)°, γ=79.109(6)°, V=1284.5(6)?3, D=1.542g·cm-3, F(000)=614, and Z=2. R1=0.0776 and wR2=0.2235(I >2σ(I)). The copper atom is five-coordinate with square-based pyramidal geometry and involves two nitrogen atoms from bpy, two oxygen atoms from cfc and one nitrogen atom from pip anion. The stacking effect between cfc and bpy ligands from two neighboring molecules was observed. Both ligand and complex were assayed against gram-positive and gram-negative bacteria by doubling dilutions method, the complex shows the same minimal inhibitory concentration (MIC) as the corresponding ligand against S.Aureus and E.Coli bacteria. The inhibitory effect of the ligand and complex on leukemia HL-60 cell line and liver cancer BEL-7402 cell line have been measured by using MTT (Methyl-Thiazol- Tetrozolium) and SRB (Sulphurhodamin B) assay methods. The results indicated that the complex has strong inhibitory effect on HL-60 cell line and on BEL-7402 cell line. CCDC: 191087. 相似文献
