Abstract

The present work reports the synthesis and structural elucidation of six novel copper(II) complexes with 2-acetylpyridine semicarbazone (HL¹) and 2-acetylpyridine N(4)-phenyl semicarbazone (HL²). In all compounds, the semicarbazone ligands were find tridentate with NNO-donor atoms. The single crystal X-ray diffraction analysis showed the influences of the different copper salt starting reagent in the crystal structures. A packing architectures analysis has been undertaken to delineate the role of relevant noncovalent interactions. The π···π stacking interactions and hydrogen bonds were analyzed using the Hirshfeld surface and fingerprint plots. In addition, the compounds were also characterized by physicochemical and spectroscopic methods.

摘要

本工作报告了六种新型的铜（II）与2-乙酰吡啶半卡巴semi（HL ¹）和2-乙酰吡啶N（4）-苯基半卡巴zone（HL ²）的合成和结构解析。在所有化合物中，发现氨基脲的三齿配体与NNO是三齿的-供体原子。单晶X射线衍射分析显示了不同铜盐起始剂对晶体结构的影响。进行了包装结构分析以描述相关的非共价相互作用的作用。使用Hirshfeld表面和指纹图分析了π··π堆积相互作用和氢键。此外，还通过物理化学和光谱法对化合物进行了表征。
