摘要

以6-苯基吡啶-2-羧酸（HL1）、1h -吡唑[3,4-b]吡啶-3-胺（L2）、氢氧化钠和四水合硝酸镉Cd（NO₃）₂·4H₂O为原料合成了一种新的镉（II）配合物[Cd(L1)2(L2)2(H2O)2]。利用元素分析、红外光谱、紫外可见光谱、热重分析和单晶x射线衍射等方法对配合物的结构进行了全面分析。单晶分析表明，Cd（II）配合物与来自L1配体的两个氧原子和两个氮原子以及来自L2配体的两个氮原子六配位，因此呈现扭曲的八面体几何形状。Hirschfeld表面分析表明，H···H相互作用对表面的贡献最大（44.7%）。乙醇中Cd（II）配合物的发光特性表明，在373 nm激发下，其发光峰强度为477 nm。此外，Cd（II）配合物的催化效率表明，它是一种有效的催化剂，在保持良好的选择性氧化苄醇的同时，实现了53%的中等产率。

Synthesis, structural characterization, Hirschfeld surface analysis and catalytic application of a new cd(II) complex bearing 1H-pyrazolo[3,4-b]pyridine-3-amine and pyridine carboxylic acid

A new cadmium(II) complex, abbreviated as [Cd(L₁)₂(L₂)₂(H₂O)₂], was synthesized by reacting 6-phenylpyridine-2-carboxylic acid (HL₁), 1H-pyrazolo[3,4-b]pyridine-3-amine (L₂), sodium hydroxide, and cadmium nitrate tetrahydrate Cd(NO₃)₂·4H₂O. The structure of the complex was thoroughly analyzed using elemental analysis, infrared spectroscopy, UV–visible spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction. The single-crystal analysis shows that the Cd(II) complex hexacoordinated with two oxygen atoms and two nitrogen atoms from the L₁ ligands, along with two nitrogen atoms from the L₂ ligands, and thus assume a distorted octahedral geometry. Hirschfeld surface analysis reveals that H···H interactions make the most significant contribution to the surface (44.7 %). The luminescent properties of the Cd(II) complex in ethanol revealed a prominent luminescence emission with a peak intensity at 477 nm upon excitation at a wavelength of 373 nm. In addition, the catalytic efficiency of the Cd(II) complex indicated it is an effective catalyst, achieving a moderate yield of 53 % while maintaining good selectivity for the oxidation of benzylic alcohol.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
