Possible Peierls Distortion Through Re2 Dimer Formation in the LaNiO2‐Type Nitrides LnReN2 (Ln = Pr, Nd)

open access: yesAngewandte Chemie International Edition, EarlyView.
This study presents the high‐pressure synthesis of two new anion‐vacancy‐ordered perovskite‐related nitrides, PrReN2 and NdReN2, featuring distorted LaNiO2‐type structures. X‐ray and neutron diffraction reveal a structural distortion driven by dimerization of Re‐chains, while electronic structure calculations reveal the simultaneous presence of ...

Salt Cluster With Surface Defect Shows Anomalous Acid–Base Chemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
The acid displacement of formic acid in sea‐salt aerosols, releasing HCl, challenges conventional acid–base chemistry. Our gas‐phase experiments show that this reaction occurs on pure NaCl cluster ions in the absence of water. Surface defects of the NaCl cluster ions enable this reaction via enhanced electrostatic interactions of the salt ions with the

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

open access: yesAngewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.
