Three new triazine compounds [Co1.5(H3TDPAT)(H2O)3]·6H2O (1), [Co2(TCPT)(μ2-H2O)2]·OH (2), and [Ni3(TCPT)]·3OH (3) were designed and synthesized via the reaction of the symmetrical triazine ligand connected by C–N–C and C–O–C bonds with triazine poly(carboxylic acid)s ligands as the side arms: H6TDPAT (H6TDPAT = 2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine) and H3TCPT (H3TCPT = 2,4,6-tris(4-carboxyphenoxy)-1,3,5-triazine) as well as the corresponding metal salts under the solvothermal condition. Three triazine polycarboxylate frameworks were characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy, thermogravimetric analysis, X-ray powder diffraction, and solid fluorescent spectra in detail. The structural analysis results showed that the three-dimensional porous cage framework of compound 1 was constructed by three different polyhedral cages connected with [Co(COO)4(H2O)2] building blocks. One of the compounds, 2, is formed by twin propeller Co2(μ2-H2O)(COO)3 building blocks connecting two-dimensional layers and the intermolecular π–π interactions involved the triazine rings between the layers. While the structure of compound 3 is similar to that of 2, assembly is by Ni(COO)3 building blocks and adjacent layers of the face-to-face π–π interaction between the triazine rings. In order to explore functional properties, the catalytic reduction of p-nitrophenol (PNP) of compounds 1–3 was investigated. They exhibit excellent catalytic activity of more than 95% for reduction of PNP with a dose of 2.5 mg of the compounds.

Mx(COO)y 结构单元构建的高对称性 Co/Ni 三嗪聚羧酸盐多元骨架：对硝基苯酚的表征和催化性能评价
三个新的三嗪化合物[Co 1.5 (H 3 TDPAT)(H 2 O) 3 ]·6H 2 O ( 1 ), [Co 2 (TCPT)(μ 2 -H 2 O) 2 ]·OH ( 2 ), 和[Ni 3 (TCPT)]·3OH ( 3 )是通过C-N-C和C-O-C键连接的对称三嗪配体与三嗪聚羧酸配体反应设计合成的臂：H 6 TDPAT（H 6 TDPAT = 2,4,6-三（3,5-二羧基苯基氨基）-1,3,5-三嗪）和 H 3 TCPT（H 3TCPT = 2,4,6-三(4-羧基苯氧基)-1,3,5-三嗪)以及溶剂热条件下相应的金属盐。通过元素分析、红外光谱、紫外光谱、热重分析、X射线粉末衍射和固体荧光光谱对三种三嗪聚羧酸酯骨架进行了详细表征。结构分析结果表明，化合物1的三维多孔笼骨架由三个不同的多面体笼与[Co(COO) 4 (H 2 O) 2 ]结构单元连接而成。其中一种化合物2是由双螺旋桨 Co 2 (μ 2 -H 2 O)(COO)连接二维层的3 个构建块和分子间 π-π 相互作用涉及层之间的三嗪环。虽然化合物3的结构与2相似，但组装是通过 Ni(COO) 3结构单元和相邻层的三嗪环之间的面对面 π-π 相互作用。为了探索功能特性，研究了化合物1-3的对硝基苯酚( PNP)的催化还原。它们在 2.5 mg 化合物的剂量下表现出超过 95% 的 PNP 还原催化活性。
