摘要

合成了3种新型Co（II）基配位化合物1-3，并通过单晶x射线衍射、红外光谱、粉末x射线衍射、热重分析、元素分析和紫外-可见吸收光谱对其进行了表征。有趣的是，化合物1和2为0周期结构，而化合物3为1周期网络结构。弱相互作用（氢键和CH⋯π相互作用）可以有效地稳定这些化合物的整个结构。并对这三种超分子框架的拓扑结构进行了分析。结果证实了弱相互作用在超分子结构中起重要作用。利用Hirshfeld表面分析可视化了弱相互作用，并构建了化合物1和2的能量框架。

Syntheses, characterization and Hirshfeld surface analyses of three new Co(II)-based coordination compounds with distinctive structures

Three novel Co(II)-based coordination compounds 1–3 have been synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy, powder X-ray diffraction, thermogravimetric analyses, element analysis and UV–vis absorption spectroscopy. Interestingly, compounds 1 and 2 exhibit 0-periodic structures, while compound 3 is a 1-periodic network structure. The weak interactions (hydrogen bonding and CH⋯π interactions) can effectively stabilize the entire structures of these compounds. The topology structures of these three supramolecular frameworks are also analyzed. The results confirm that the weak interactions play an important role in the supramolecular framework. The weak interactions are visualized by Hirshfeld surface analyses, and the energy frameworks of compounds 1 and 2 are constructed.

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.
