1,7‐Digallatetracarborane: Between Nucleophilic closo‐Cluster and “Inverse Sandwich” Digallylene
Angewandte Chemie, EarlyView.A dianionic π‐ligand is used to make a Janus‐type twofold complex with low‐valent gallium Ga(+I). The resulting compound can be seen as and reveals the reactivity of both: a Wade‐type closo‐carborane cluster with nucleophilic Ga‐sites, as well as π‐ligand stabilized Ga(I) atoms in an inverse sandwich compound.

Heavier Alkyne‐Ni0 Complexes, [R2E2·Ni] (E = Sn, Pb), Exhibiting σ‐Complex Character
Angewandte Chemie, EarlyView.Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ‐complexes, driven by ligand‐induced constraints and the established poor π‐bonding in heavier alkyne analogues.

Mitochondria‐Targeting Moieties Based on N‐Tethered Pyridinium Cations
Angewandte Chemie, EarlyView.Pyridinium cations were benchmarked as mitochondria‐targeting moieties in a panel of N‐tethered fluorescent‐, bioactive‐, and inert‐cargo conjugates. 3,5‐Diphenylpyridinium (DPPy+) is a competent triphenylphosphonium (TPP+) surrogate, combining high mitochondria‐targeting efficiency with lower intrinsic effects on mitochondrial function.

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2
Angewandte Chemie, EarlyView.By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

A Non‐Covalent [4Fe–4S]/[2Fe] Interface in HydF Guides [FeFe]‐Hydrogenase Maturation
Angewandte Chemie, EarlyView.Bridged or not? 57Fe NRVS reveals a non‐covalent, electronically coupled interaction between the HydF [4Fe–4S] cluster and the [2Fe] precursor. Boltz‐2 structure predictions suggest that the cubane organizes lipoate‐dependent Hmet chemistry, positioning intermediates for assembly of the CH2–NH–CH2 bridge during H‐cluster biosynthesis.
