In this communication, we revisit one of E. O. Fischer’s seminal discoveries to solve a textbook question: is the iron(0) complex [Fe(C6Me6)2] an 18-valence-electron complex with a ‘ring-slip’ (η6,η4) configuration like its heavier congener [Ru(C6Me6)2] or a 20-valence-electron complex with an (η6,η6) configuration like its neighbor [Co(C6Me6)2]+? Using modern single-crystal X-ray diffraction techniques intertwined with density functional theory, we present the first crystallographically characterized iron(0) bis(arene) complex, [Fe(C6Me6)2], demonstrating that iron opts to violate the 18-electron rule, favouring two aromatic arene ligands.

The unique photophysical properties of heavy T-shaped Sb and Bi trisamides are reported. A ligand-to-pnictogen charge-transfer excitation from a redox-active NNN pincer to a vacant pnictogen p-orbita...

We report the synthesis and comprehensive characterisation of a square-planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N-pincer ligand. This system enables element...

Molecular complexes of iron in the rare +1 oxidation state have been shown to be efficient catalysts for industrially relevant chemical transformations, typically associated with the increasingly unsu...

A modular synthetic approach affords a series of cationic cobalt and manganese carbonyl half-sandwich complexes bearing onium-substituted diphosphacyclobutadienyl ligands. In this strategy, the onium....

Im Jahr 2025 waren aller guten Dinge der Hauptgruppenchemie drei: ein dreifach geladenes Triborattrianion, ein Molekül mit linearer Al3-Einheit, das dritte Erdalkalimetall, das Stickstoff bindet, ein ...

We present the synthesis and characterization of the parent isolable monomeric triplet titanocene complex, stabilized by the N-heterocyclic carbene (NHC) IMe4. Investigated by SQUID magnetometry and…

The ubiquity of N-heterocyclic carbenes (NHCs) in chemical research typically arises from their potent stabilizing capabilities and role as innocent spectators to stabilize otherwise non-bottleable co...

In this work, we disclose the synthesis and characterization of non-acid/base-stabilized anionic oxoboranes [MesTer2BO][K(L)] (MesTer = –C6H3-2,6-(2,4,6-Me3-C6H2)2, L = [2.2.2]-cryptand or 18-crown-6)...
