摘要
以1,2-亚乙基二吡啶鎓盐为结构导向剂合成了一维有机-无机杂化配聚物{(BPE)3[Ag4Br4(SCN)6]}n(BPE为1,2-亚乙基二吡啶鎓阳离子),通过元素分析、红外光谱和X-射线单晶衍射对其结构进行了表征.结构解析表明:该聚合物属单斜晶系,P21/n空间群,晶胞参数a=0.973 69(1)nm,b=0.909 07(1)nm,c=3.114 5(4)nm,β=91.659 0(1)°,Z=4.聚合物中有2类晶体学独立的Ag(Ⅰ)离子,每个Ag(Ⅰ)离子均为扭曲的四面体配位构型,通过Br原子和SCN-桥联形成一维聚阴离子链[Ag4Br4(SCN)6]n6n-,2类晶体学独立的BPE在bc平面分别贯穿链内的空腔和相邻链间的空隙之中。
A one-dimensional inorganic-organic hybrid coordination polymer,{(BPE)3[Ag4Br4(SCN)6]}n,has been synthesized by using BPE as structural direction reagents.It has been characterized by elemental analysis,IR and X-ray single crystal diffraction.The title polymer crystallizes in monoclinic space group P21/n,with a=0.973 69(1) nm,b=0.909 07(1) nm,c=3.114 5(4) nm,β =91.659 0(1)° and Z=4.In the polymer,there are two crystallographically independent Ag(Ⅰ) ion,each Ag(Ⅰ) ion displays distorted tetrahedral geometry.By bridging Br atoms and SCN-with Ag(Ⅰ) ions,one-dimensional polymeric chain [Ag4Br4(SCN)6]n6n-is formed,and two crystallographically independent BPE penetrate the cavity of the chain and interstice between adjacent chains in bc plane,respectively.
