摘要
以2,2′:6′,2″—三联吡啶(tpy),Eu(NO3)2.6 H2O为原料合成了标题配合物,配合物由一个Eu(Ⅲ)离子、一个三联吡啶、两个硝酸根离子、三个水分子组成配位一价阳离子内界,另一个硝酸根为外界.晶体结构研究表明配合物晶体属三斜晶系,P-1空间群,晶胞参数a=8.880 3(6)nm,b=11.223 5(7)nm,c=11.746 1(7)nm,α=88.850 0(10)°,β=69.103 0(10)°,γ=74.604 0(10)°,V=1050.83(12),Z=2,R=0.015 3,wR=0.059 8,Eu3+的配位数为10并形成双帽四方反棱柱的配位构型.
The title complex [Eu（NO3）2（tpy）（H2O）3]NO3 has been synthesized by 2,2′：6′,2″-terpyridyl（tpy） and Eu（NO3）2·6H2O,the complex was composed with one Eu3＋,one tpy,one two nitrate ion and three water molecular inside,outside of it was a nitrate ion.Its crystal and molecular structures were determined by X-ray diffraction methods.The crystal crystallizes in the triclinic system,space group P-1 with a=8.880 3（6） nm,b=11.223 5（7） nm,c=11.746 1（7） nm,α=88.850 0（10）°,β=69.103 0（10）°,γ=74.604 0（10）°,V=1 050.83（12）,Z=2,R=0.015 3,wR=0.059 8.The central europium ion is ten-coordinated and its coordination polyhedron can be described as a dicapped square antiprism.
