A Crystalline Bismuth(II) Radical Anion: Synthesis, Characterization, and Reactivity
Abstract We report the synthesis of a planarized tris‐amidobismuthane supported by a rigid, bulky NNN pincer ligand, which enforces a T‐shaped geometry at the bismuth center. The Bi(NNN) complex features a low‐lying LUMO with distinct Bi(6p) orbital character as shown by DFT calculations. Cyclic voltammetry reveals a fully reversible one‐electron reduction at E 1/2 = –1.85 V versus Fc 0/+ in THF. Chemical reduction with KC 8 in the presence of 4,7,13,16,21,24‐hexaoxa‐1,10‐diazabicyclo[8.8.8]hexacosane (222‐crypt) enables the isolation of an unprecedented Bi(II) radical anion in high isolated yields. Multi‐frequency EPR, X‐ray absorption spectroscopy and SQUID magnetometry complemented by theoretical calculations confirm localization of the unpaired electron on the bismuth center. Preliminary reactivity studies display radical reactivity as shown by single‐electron transfer chemistry and radical coupling reactions.

Lattice Oxygen Activation Through Redox‐Induced δ‐MnO <sub>2</sub> /Co <sub>3‐x</sub> Mn <sub>x</sub> O <sub>4</sub> Interfaces for Enhanced N <sub>2</sub> O Decomposition
Abstract N 2 O decomposition over spinel catalysts suffers from a spin‐forbidden oxygen recombination step, resulting in substantial kinetic barriers of O 2 formation. Herein, we present a redox‐induced interfacial engineering strategy to activate lattice oxygen in spinel oxides, thereby effectively overcoming the kinetic constraints associated with oxygen recombination. In a Co 3 O 4 ‐based model system, controlled permanganate etching partially substitutes Mn into octahedral Co 3+ sites, while simultaneously generating heterointerfaces. The enhanced hybridization between Co 3 d and O 2 p orbitals and high Co–O–Mn covalency induced by the interface between δ‐MnO 2 and Co 3‐x Mn x O 4 , lead to the formation of highly active lattice oxygen species adjacent to the interface. 18 O isotope labeling experiment further confirms a dominant lattice‐oxygen‐mediated Mars–van Krevelen mechanism for N 2 O decomposition, whereas pristine Co 3 O 4 predominantly follows the Langmuir–Hinshelwood mechanism. Therefore, the optimized catalyst exhibits enhanced N 2 O decomposition activities, maintaining stability under impurity‐rich conditions. This work offers a promising approach for the rational design of efficient catalysts for N 2 O abatement and provides mechanistic insights into redox‐induced lattice oxygen activation.
