A Crystallographic Shear Driven by Oxygen Insertion in (LuFeO3)nLuFe2O4

ChemistryEurope, EarlyView.
Layered structures (LuFeO3)nLuFe2O4 exhibit a common structural transformation upon oxygen uptake. Although the LuFeO3 units do not directly participate in oxygen insertion, these inactive layers nevertheless influence the temperature at which oxygen absorption occurs.

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

Chemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

Interplay between Superconductivity and Magnetism in Rb0.8Fe1.6Se2 under Pressure

, 2011
High-pressure magnetization, structural and 57Fe M\"ossbauer studies were performed on superconducting Rb0.8Fe1.6Se2.0 with Tc = 32.4 K. The superconducting transition temperature gradually decreases on increasing pressure up to 5.0 GPa followed by a ...
