    “…The synthesis of electron‐poor mono‐, di‐ and tri(imidazolium)‐substituted Cp‐ylides is presented and their electronic properties are discussed based on NMR spectroscopy, X‐ray structure analyses, electrochemical investigations and DFT calculations as well as by their reactivity toward [Ru(CH(3)CN)(3)Cp*](PF(6)). With mono‐ and di(imidazolium)‐substituted cyclopentadienides the respective monocationic and dicationic ruthenocences are formed (X‐ray), whereas tri(imidazolium) cyclopentadienides are too electron‐poor to form the ruthenocenes. …”

    “…The electronic structure revealed that Be(3)Ru has a pseudo‐gap close to the Fermi level. A strong charge transfer from Be to Ru was observed from the analysis of electron density within the Quantum Theory of Atoms in Molecules (QTAIM) framework and polar three‐ and four‐atomic Be−Ru bonds were observed from the ELI−D (electron localizability indicator) analysis. …”

    “…In this work, we systematically investigate the electronic responses of ZrRuAs to external pressure. At ambient pressure, ZrRuAs show superconductivity with T(c) ~ 7.74 K, while a large upper critical field ~ 13.03 T is obtained for ZrRuAs, which is comparable to the weak-coupling Pauli limit. …”
