摘要:

以4,4'-三苯胺二甲酸(H2L)为多齿有机羧酸与1,4-二(吡啶-4-亚甲基)哌嗪(bpmp)和硝酸镉在溶剂热条件下反应, 得到2种晶体的混合物, 经物理拆分后得到无色透明的片状晶体{[CdL(bpmp)(H2O)]·H2O·DMF}n(1) 和淡黄色块状晶体{[Cd2L2(bpmp)2]·3H2O·2DMF}n(2). 通过单晶及粉末X射线衍射、 红外光谱、 元素分析、 热重分析和荧光光谱对这2种化合物进行了表征. 结果表明, 化合物1属于单斜晶系, P21/c空间群, 其骨架为具有{65·8}拓扑结构的四重互穿三维网络; 化合物2属于三斜晶系, P1ˉ空间群, 其结构为含有螺旋链的二维层, 其骨架具有{36·46·53}拓扑结构.

Abstract:

The solvothermal reactions of Cd(NO3)2 with 4,4'-(phenylazanediyl)dibenzoic acid(H2L) and 1,4-bis(pyridin-4-ylmethl)piperazine(bpmp) gave rise to a mixture of colorless sheet-like crystals {[CdL(bpmp)(H2O)]·H2O·DMF}n(1) and yellowish bulk crystals {[Cd2L2(bpmp)2]·3H2O·2DMF}n(2), which were mechanically separated. Both compounds were structurally determined by single-crystal X-ray diffraction. Compounds 1 and 2 were also characterized by FTIR spectroscopy, elemental analyses, thermal analysis, and powder X-ray diffraction(PXRD). Compound 1 exhibits a 4-fold interpenetrating 3D framework with a {65·8} topology. Compound 2 consists of 1D [Cd2L2]n helical chains linked by bpmp ligands to form a 2D network with a {36·46·53} topology.

Key words: 4,4'-(Phenylazanediyl)dibenzoic acid, 1,4-Bis(pyridin-4-ylmethl)piperazine, Metal-organic framework, Solvothermal synthesis
