This study aimed to synthesize and characterize a copper complex using various analytical techniques. The synthesized complex was confirmed through IR spectroscopy and further characterized using X-ray diffraction, which revealed complex crystallized in the monoclinic crystal system with the P21 space group. The complex exhibited hydrogen bonding, with Hirshfeld analysis indicating a 7.1% contribution from the surfaces. The study also found that H···H interactions accounted for 59.6% of the significant amount of interaction in the surfaces. Overall, this investigation provides valuable insights into the structural properties and interactions of copper complexes. These findings provide valuable insights into the structural properties and interactions of copper complexes, which can contribute to the development of new materials with unique properties and potential applications in fields such as catalysis, electronics, and medicine. The ability to synthesize and characterize these complexes can lead to the discovery of novel copper complexes with even more remarkable properties. Further research in this area could build upon the findings of this study and advance our understanding of the structural properties and interactions of copper complexes.


Main Subjects

In conclusion, this research effectively produced a copper complex and verified its structures through IR spectroscopy. The complexes were further examined using X-ray diffraction, which disclosed that the [Cu(Hpbdo)(pbdo)(OCH3)] complex crystallized in the monoclinic crystal system with the P21 space group. The complexes exhibited Hydrogen bond, and Hirshfeld analysis indicated that the surfaces hydrogen bond contribution was 7.1%. Moreover, the study discovered that the significant amount of interaction in the surfaces was associated with H···H interactions, which accounted for 59.6% in the complex. In general, this investigation offers valuable insights into the structural properties and interactions of these copper complexes.
