Abstract:
A detailed computational and spectroscopic investigation of the ferrocene-pyrazoline hybrid FDDHE is presented to elucidate its electronic structure and bonding characteristics. Density functional theory calculations were employed in conjunction with natural bond orbital (NBO), electron localization function (ELF), atoms-in-molecules (AIM), localized and fuzzy bond order, molecular electrostatic potential, and vibrational analyses. The results reveal pronounced charge delocalization across the conjugated framework, a strongly electrophilic enone fragment, and significant metal-ligand electronic communication involving the ferrocene unit. Notably, low-occupancy nonclassical Rydberg-type orbitals contribute to charge redistribution and stabilization during redox-relevant electronic rearrangements. Topological analyses confirm the presence of nonclassical bonding features and persistent electrophilic character within the molecular framework. The combined spectroscopic and electronic descriptors establish a coherent structure-reactivity profile for FDDHE and provide a rigorous theoretical basis for understanding its redox and bonding behavior within ferrocene-pyrazoline systems.
