A one-dimensional coordination polymer{[Cd2 (L)(H2O)6 ]·6 H2O}n was synthesized from Cd (NO3)2 ·4H2O,N,N'-bis(5-Methylisophthalic acid)amion]benzoic acid (H4L)by hydrothermal method.It confirmed via singe-crystal X-ray diffraction that the compound 1 crystallizes in the monoclinic system and space group P-1.Crystal data:a=8.8691(11)?,b=10.0747(12)?,c=10.1404(11)?,α=73.281(10)°,β=83.202(10)°,γ=74.597(11)°,V=835.74(17)?3 ,Z=2,Dc =1.747 g/cm-3 ,F(000)=444,GOOF=1.128,R1=0.1186,wR2=0.3767[I>2σ(I)].The structure of compound 1 was also char-acterized by X-ray powder diffraction,elemental analysis and infrared spectrum and the solid-state fluo-rescence.In the compound 1 ,Cd2+ ions coordinated to L4- ligands,finally form one-dimensional layered network.%以金属盐Cd(NO3)2·4H2O、有机配体1,4-二(5-甲基间苯二甲酸)哌嗪(H4 L)为原料,在水热条件下合成出一种具有一维梯形结构的配位聚合物{[Cd2(L)(H2O)6]·6H2O}n(1),并通过红外光谱、元素分析、X-射线单晶衍射及X-射线粉末衍射对该化合物进行了结构表征,并进一步研究了其固体荧光性质.结构分析表明,化合物1属于三斜晶系,P-1空间群,晶体学参数:a=8.8691(11)?,b=10.0747(12)?,c=10.1404(11)?,α=73.281(10)°,β=83.202(10)°,γ=74.597(11)°,V=835.74(17)?3,Z=2,Dc=1.747 g/cm-3,F(000)=444,GOOF=1.128,R1=0.1186,wR2=0.3767[I>2σ(I)].在化合物1中,有机配体L4-与Cd2+离子在c轴方向相互连接,构成一维梯形结构的配位聚合物.
