柔性三齿配体1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene(TITMB)和1,3,5-tris(triazol-1-ylmethyl)-2,4,6-trimethylbenzene(TTTMB)与金属镉(Ⅱ)和锌(Ⅱ)分别反应,合成了配合物{[Cd_3(SO_4)_4(TITMB)_2(H_2O)_4][Cd(H_2O)_6]·2CH_3OH}_n(1)和{[Zn(TTTMB)(HCOO)_2]·CH_3OH}_n(2)。配合物1和2均采用单晶X射线衍射、红外光谱、固态荧光、热重分析和元素分析进行了表征。在配合物1中,存在着由硫酸根离子和Cd(Ⅱ)构成的一维链,其再与配体TITMB配位形成二维层状结构,[Cd(H_2O)_6]~(2+)位于层与层中间平衡电荷。配合物2具有典型的63二维蜂窝状拓扑结构。配合物1和2中的二维层状结构,均通过氢键作用延伸成为三维结构。配合物1和2均具有较高的热稳定性,并且在固态下释放蓝色荧光。
Flexible tridentate ligands 1,3,5-tris (1-ylmethyl) -2,4,6-trimethylbenzene (TITMB) and 1,3,5-tris- The complex of [Cd_3 (SO_4) _4 (TITMB) _2 (H_2O) _4] [Cd (H_2O) _6] · 2CH_3OH} was synthesized by the reaction of 6-trimethylbenzene (TTTMB) with cadmium (Ⅱ) and zinc (Ⅱ) _n (1) and {[Zn (TTTMB) (HCOO) _2] · CH_3OH} _n (2). Complex 1 and 2 were characterized by single crystal X-ray diffraction, infrared spectroscopy, solid-state fluorescence, thermogravimetric analysis and elemental analysis. In complex 1, there exists a one-dimensional chain composed of sulfate ion and Cd (Ⅱ), which is coordinated with ligand TITMB to form two-dimensional layered structure [Cd (H 2 O) 6] Located in the middle of the layer and the balance of charge. Complex 2 has a typical 63 two-dimensional honeycomb topology. The two-dimensional layered structures in complexes 1 and 2 all extended to three-dimensional structure by hydrogen bonding. Both complexes 1 and 2 have higher thermal stability and release blue fluorescence in the solid state.
