- Abstract
In the current work, we introduce a novel class of molecules termed carbo -metallabenzenes, and their aromaticity has been comprehensively analyzed. The molecules were strategically designed with the insertion of acetylene (C≡C or C
2 ) units in some selected metallabenzenes. Furthermore, if a second metallic unit is inserted (replacing a sp2 carbon) in the carbo -metallabenzenes rings, a new family of carbo -mers is generated, and this second group has been named as carbo -dimetallabenzenes. The primary objective of this work is to ascertain, through various methodologies, whether these newly proposed molecules retain the aromatic characteristics observed in carbo -benzene. The methodologies employed for bond analysis and aromaticity exploration include the analysis of the molecular orbitals, energy decomposition analysis, electron density of delocalized bonds, magnetically induced current density, and the induced magnetic field ( Bind ). This study sheds light on that the insertion of the metallic centers reduces the electronic delocalization and their aromaticity is, in some cases, comparable with the electronic delocalization of the inorganic iminobora -borazine and also provides valuable insights into their electronic structure through a multifaceted analysis., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.
