Special Issue Information

Dear Colleagues,

Organometallic chemistry stands as a captivating and dynamic branch of chemical science, dedicated to the synthesis, structural characterization, and functional exploration of compounds that integrate both metal and organic components. These unique compounds, including metal–organic frameworks, cages, and clusters, play a pivotal role in advancing diverse fields such as coordination chemistry, supramolecular chemistry, catalytic chemistry, materials science, and synthetic chemistry. The evolution of organometallic chemistry has transcended traditional synthesis, now extending its reach into the realm of intelligent functional materials.

In this Special Issue, we spotlight recent advancements in the synthesis, functionalities, and structural property relationships of organometallic materials. By seamlessly combining the advantageous properties of metals and organic components, these materials have been extensively studied for their applications in catalysis, optics, electronics, magnetics, and beyond. This issue not only highlights the latest breakthroughs in organometallic chemistry, but also introduces innovative concepts for the development of next-generation materials and their applications across a wide range of disciplines.

Through this collection, we aim to inspire further exploration and innovation, fostering a deeper understanding of the transformative potential of organometallic chemistry in addressing contemporary scientific and technological challenges.

The ionization of ferrocene (Fc) remains an active topic of interest due to its complex, ulti-electron character. Accurate prediction of its first ionization potential (IP) requires methods that go beyond single-particle approximations, as Koopmans’ theorem, Janak’s theorem, and the outer valence Green function (OVGF) approach prove inadequate. Using the ΔSCF method, the first IP of Fc was calculated to be ~6.9 ± 0.1 eV, which is in close agreement with experimental values (6.72–6.99 eV). To benchmark computational accuracy, 42 models were evaluated using the CCSD, CCSD(T), and B3LYP methods with Pople and Dunning basis sets, including Fe-specific modifications to better capture 3d electron behavior. The results underscore the importance of proper treatment of Fe 3d orbitals, with B3LYP/m6-31G(d) offering the best compromise between accuracy and computational efficiency. Notably, the singly occupied molecular orbital (SOMO) in Fc+ is identified as the 8a1’ orbital, which is dominated by its Fe 3d character. This orbital, although not the α-HOMO in Fc+, becomes the LUMO upon ionization. Analysis of the excess orbital energy spectrum (EOES) reveals substantial energy shifts upon ionization, particularly in Fe-centered orbitals spanning both the core and valence regions. Theoretical momentum distribution (TMD) analysis of the 8a1’ orbital further quantifies orbital differences before and after ionization, providing complementary insights in momentum space. Finally, energy decomposition analysis (EDA) shows that while most interaction energy components become less stabilizing upon ionization, steric and Pauli terms contribute a small stabilizing effect.

Databases of organic compounds are rooted in chemical formats, typically modeling chemical structures as simple graphical representations, which are easily readable by both humans and machines. This information can be handled by software and standards that have emerged in chemistry over decades and are well established. The present communication proposes that the extension of databases to encompass organometallic compounds, with coordination bonds, can be accomplished seamlessly with minor modifications, without compromising the utility of the database functionalities. Using a database for nuclear magnetic resonance (NMR) data, we demonstrate that this enables treating the organometallic compounds with the same algorithms as the organic compounds. Full article
