基于柔性毗啶基配体和钒酸盐,合成得到了一个非中心对称的杂化化合物[Cu14(bpp)4(Vv6O17)](1)(bpp=1,3-二(4-吡啶基)丙烷),并通过元素分析、红外光谱、X-射线单晶衍射、热重分析等测试对其进行了表征.晶体数据表明该化合物属于正交晶系,Pca21空间群.在化合物1中,一维链状的多钒酸根与[CuI(bpp)]单元通过Cu-O键连接形成沿ab平面的层,这些层进一步通过Cu(Ⅰ)…Cu(Ⅰ)弱相互作用(Cu(Ⅰ)…Cu(Ⅰ)距离为0.281 nm)连接成一个三维的框架结构.

A noncentrosymmetrical hybrid complex[CuI4(bpp)4(V6vO17](1)(bpp=1,3-bis(4-pyridyl)propane) based on the flexible polypyridyl ligand and vanadate has been synthesized and characterized by element analysis,IR spectra,single-crystal X-ray diffraction,thermo gravimetric analysis.The crystallographic data shows that complex 1 crystallizes in orthorhombic space group Pcn21 with a=2.392 0(3) nm,b=1.311 87(16) nm,c=1.968 9(2)nm,V=6.1786(13) nm3,C52H56N8Cu4O17V6,Mr=1 624.85,Dc=1.747 g·cm-3,μ(Mo Kα)=2.283 mm-1,F(000)=3 256,GOF=0.928,Z=4,the final R1=0.069 2 and wR2=0.152 6 for,I＞2σ(I).In 1,the one dimensional chains composed of vanadates clusters are connected by the[CuI(bpp)]+ cations to form a two dimensional layer along the ab plane.The two dimensional layers are further linked through weak CuI…CuI interaction with the CuI…CuI distance of 0.28 1 nm,resulting in a three dimensional framework.
