报道了配合物[Cu(DPQ)2(ClO4)](ClO4)·H2O·0.5CH2Cl2·CHCl3(DPQ=2,3-双-(2-吡啶)喹喔啉)的合成及表征(元素分析、电导、红外和紫外光谱).室温X-射线单晶衍射分析结果表明,标题配合物(C37.5H28Cl6CuN8O9,分子量=1010.92)处于正交晶系,Pmmn空间群,a=1.0547(2)nm,b=1.1819(2)nm,c=2.0014(4)nm,V=2.4949(9)nm,Z=2,Dc=1.346g/cm3,F(000)=1024,μ(MoKα)=0.813mm-1.最终精修得到的R及wR因子分别为0.0452和0.1070,独立衍射点个数为2367.配合物由分立的[Cu(DPQ)2(ClO4)]+阳离子,未配位的ClO4-阴离子和溶剂分子组成.中心Cu 离子分别与两个DPQ配体上的4个吡啶氮原子以及高氯酸根上的一个氧原子配位,其配位几何构型为理想四方锥.两个DPQ配体仅通过吡啶氮原子与Cu 离子螯合配位,形成两个七元环.此外,结构中两个平行喹喔啉环之间存在着π…π堆积相互作用.
The synthesis and characterization of Cu (DPQ) 2 (ClO4)] (ClO4) · H2O · 0.5CH2Cl2 · CHCl3 (DPQ = 2,3-bis- The results show that the title complex (C37.5H28Cl6CuN8O9, MW = 1010.92) is in orthorhombic, Pmmn space group with a = 1.0547 (2) nm, b = 1.1819 (2) nm, c = 2.0014 (4) nm, V = 2.4949 (9) nm, Z = 2, Dc = 1.346g / cm3, F (000) = 1024, μ (MoKα) = 0.813mm-1 The final R and WR factors were 0.0452 and 0.1070, respectively, and the number of independent diffraction spots was 2367. The complex consisted of discrete [Cu (DPQ) 2 (ClO4)] + cation, uncoordinated ClO4- anion and Solvent molecules. The central Cu ions coordinate to four pyridine nitrogen atoms on two DPQ ligands and one oxygen atom on perchlorate respectively, and the coordination geometry is ideal tetragon. Two DPQ ligands The pyridine nitrogen atom chelates with Cu ions to form two seven-membered rings.In addition, there exists π ... π stacking interaction between two parallel quinoxaline rings in the structure.
