Expanding Cyanide-Bridged Weakly Coordinating Anions Through the Brominated Silver Salt Ag[BCNB Br ]
1 Introduction Weakly coordinating anions (WCAs) are indispensable building blocks for accessing highly reactive cationic species and enabling their characterization. Effective WCAs combine minimal coordinating ability with high stability toward oxidizing conditions and electrophiles, typically provided by large, robust anions with delocalized charge and minimal nucleophilic sites [1].
Coexistence of Metallocene Cations and Anions
Introduction Click to copy section linkSection link copied! The synthesis and characterization of ferrocene (FcH) in 1951 have been widely marked as the birth of organometallic chemistry, sparking the rich chemistry of metallocenes.
Osmium(VI) Nitrido Complexes with Perfluorinated Alcoholate Ligands: Expanding Ligand Scope through a Simple Silver Oxide‐Mediated Synthesis Route
1 Introduction The incorporation of fluorinated groups into organic molecules has been demonstrated to exhibit a profound influence on nearly all of their physical properties.[1-6] In this regard, there has been a significant demand to develop more efficient processes to access (per)fluorinated compounds, and specifically toward the synthesis of well-defined metal complexes carrying perfluorinated groups as practical catalytic transfer reagents.[7-9] However, the presence of perfluorinated...
Stimulus-responsive metallocenes: a photo/thermal switch enabled by the perfluorinated Cp* ligand The electron-deficient ferrocene [Fe(C5H5)(C5(CF3)5)] is complemented by the synthesis and full characterisation of the analogous bench-stable ruthenocene [Ru(C5H5)(C5(CF3)5)]. These complexes have been studied with respect to the substitution lability of the perfluorinated Cp* ligand under mild conditions.

Crystallographic Evidence for Bi(I) as the Heaviest Halogen Bond Acceptor
Introduction Click to copy section linkSection link copied! In recent years, heavier main group elements have become increasingly popular for the activation of small molecules. (1) In this context, bismuth is of great interest due to its low toxicity and rich redox chemistry, the latter showing parallels with transition metal chemistry. (2,3) Recently, interest in the reduced oxidation state +I of bismuth has significantly increased.

Structural diversity of supramolecular networks formed between polycyanometalates and sulfur-based chalcogen bond donors
Structural diversity of supramolecular networks formed between polycyanometalates and sulfur-based chalcogen bond donors† The co-crystallization of S-(CF3)-dibenzothiophenium (“Umemoto” – abbreviated Ume) cations and polycyanometalates with different coordination geometries yields a large structural variety of supramolecular assemblies.
CF3-Substituted Sulfonium Cations as Efficient Chalcogen Bond Donors towards Cyanometalates
CF3-Substituted Sulfonium Cations as Efficient Chalcogen Bond Donors towards Cyanometalates S-(CF3)thianthrenium and S-(CF3)dibenzothiophenium cations form potent chalcogen bonds (ChBs) with [Mo(CO)5CN]−, yielding S2N2 supramolecular motifs. Crystal structures reveal shorter S···N contacts opposite the CF3 group compared to the aryl substituents.
