Peroxide‐Assisted Solvate Engineering Enables Record‐High Birefringence in a Solar‐Blind Transparent Crystal

Angewandte Chemie, EarlyView.
H2O2‐directed solvate engineering reorganizes ∞[4HP] (4‐hydroxypyridine) chains from a crossed arrangement into a nearly parallel packing through strengthened hydrogen‐bonding interactions. The resulting peroxide‐containing crystal, 4HP·H2O2, exhibits a solar‐blind UV cutoff edge (278 nm) and giant birefringence (0.609 @ 546 nm). This work demonstrates

Evidence for a Cu(II)‐Catalysed CuAAC Reaction: A Combined Experimental and Computational Study

Angewandte Chemie, EarlyView.
A new mechanistic pathway for the CuAAC reaction has been found to operate under specific reaction conditions. The pathway is catalysed by Cu(II) through a self‐assembled dinuclear Cu(II) complex that incorporates the triazole product. Computational analysis and assessment of generality are reported.

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, EarlyView.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

Single‐Atom Control of Aromaticity and Excited‐State Dynamics in Endohedral Zirconium–Antimony Zintl Clusters

Angewandte Chemie, EarlyView.
Single‐atom growth from [Zr@Sb12]2− to [Zr@Sb13]3− disrupts the closed‐shell S2P6 superatomic configuration and markedly attenuates three‐dimensional (3D) aromaticity. Ultrafast spectroscopy further links stronger spherical aromaticity to slower excited‐state relaxation, establishing an atom‐resolved structure‐aromaticity‐dynamics relationship ...

Reductive Activation of White Phosphorus to [P4]2–, [P2]2–, and a Formal P2– Radical by Rare‐Earth Dinitrogen Complexes

Angewandte Chemie, EarlyView.
Masked divalent yttrium and gadolinium dinitrogen complexes mediate the fragmentation of white phosphorus, converting P4 into discrete dimetallic complexes of [P4]2– and [P2]2– ligands, and an unprecedented monatomic P2– radical ligand. Structural, spectroscopic, magnetic, and DFT studies reveal insight into the bonding between these unusual Pn units ...
