| 摘要: 合成了一个新颖的含ONN席夫碱配体N-水杨醛基-2-氨乙基苯并咪唑(HL)，并在甲醇体系中合成了它的配合物[Cu(L)(bipy)]ClO4(bipy为2，2′-联吡啶)。利用X-射线单晶衍射法测定了配合物的晶体结构。配合物[Cu(L)(bipy)]ClO4的晶体属于单斜晶系，C2/c空间群，a=2.585 5(8) nm，b=1.435 5(5) nm，c=1.624 2(5) nm，β=124.434(5)°，Z=8。在配合物[Cu(L)(bipy)]ClO4中，每个铜离子的配位数为5，分别和配体L的1个氧原子和2个氮原子及2，2′-联吡啶的2个氮原子配位，形成畸变的三角双锥配位环境。配合物[Cu(L)(bipy)]ClO4中的氢键和π-π相互作用将配合物[Cu(L)(bipy)]ClO4连接成二维网络结构。用红外光谱、紫外-可见光谱对配合物[Cu(L)(bipy)]ClO4进行了表征，并用循环伏安法对配合物进行了电化学性质的研究。 |

| Abstract: The crystal structure of the complex [Cu(L)(bipy)]ClO4 (HL=N-salicylidene-2-aminoethylbenzimidazole, bipy=2,2′-bipyridine) has been determined by X-ray diffraction method and refined by full-matrix least-squares methods to R=0.033 9 and wR2=0.080 4 using 5 079 reflections with I>2σ(I). The compound crystallizes in the monoclinic system, space group C2/c, with a=2.585 5(8) nm, b=1.435 5(5) nm, c=1.624 2(5) nm, β=124.434(5)° and Z=8. Each Cu(Ⅱ) ion adopts distorted N4O trigonal bipyramidal coordination geometry. The hydrogen-bonding and π-π interactions extend the complex into a quasi two-dimensional networks, and such weak interactions further stabilized the complex. FTIR, UV-Vis and CV were also used to characterize the complex. CCDC: 275659. |
