摘要(Abstract)：

以Cu(NO_3)_2·3H_2O、1,1-环己烷二乙酸(H2chda)与4,4-联吡啶(bipy)为原料,在水热条件下合成出一个配位聚合物[Cu_2(chda)_2(bipy)]_n(1),并通过元素分析、红外光谱、单晶X-射线衍射及粉末X-射线衍射对该化合物进行了表征.结构分析表明化合物1属于单斜晶系、C2/c空间群,晶胞参数为:a=19.909(3)?,b=14.266 9(18)?,c=11.705(2)?,β=125.363(5)°,V=2 711.3(7)?3,Z=4,Dc=1.665g/cm-3,μ=1.627mm-1,F(000)=140 8,R1=0.055 6,wR2=0.096 7[I>2σ(I)].在化合物1中,2个Cu~(2+)离子与4个chda~(2-)上的8个羧基氧原子配位形成螺旋桨式次级构筑单元[Cu_2(CO_2)_4].该次级构筑单元与chdc~(2-)连接形成一维链,进一步通过bipy拓展构筑成二维网络结构.
