Photoinduced bending of rod-like millimetre-size crystals of a rhodium dithionite complex with n-pentyl moieties

Rod-like millimetre-size crystals of a newly prepared rhodium dithionite complex with n-pentyl moieties bend upon photoirradiation and return to the initial shape upon heating; the roles of the flexible n-pentyl moieties as well as the photoreactive dithionite unit (μ-O2SSO2) are disclosed by single crystal X-ray diffraction.

Inorganic clusters with a [Fe2MoOS3] core—a functional model for acetylene reduction by nitrogenases

We report the first example of a wholly inorganic mimic of a part of the FeMoco active centre of nitrogenases.

A gadolinium(iii) complex that shows room-temperature phosphorescence in the crystalline state

A gadolinium(iii) complex that shows crystalline-state phosphorescence is presented; crystals color can be changed by doping of 1-naphthol.

An oxygen-sensitive luminescent Dy(iii) complex

A 1,4,7-triazacyclononane based tris-aryloxide ligand provides an unprecedented oxygen-sensitive luminescent dysprosium(iii) complex.

A High-Valent Iron(IV) Peroxo Core Derived from O2

Dioxygen-tolerant [NiFe] hydrogenases catalyze not only the conversion of H2 into 2 H(+) and 2 e(-) but also the reduction of O2 to H2O. Chemists have sought to mimic such bifunctional catalysts with structurally simpler compounds to facilitate analysis and improvement. Herein, we report a new [NiFe]-based catalyst for O2 reduction via an O2 adduct. Structural investigations reveal the first example of a side-on iron(IV) peroxo complex.

Synthesis and crystal structure of a dinuclear, monomeric Mn(II) p-semiquinonato complex

Herein, we report the first crystal structure of a monomeric p-semiquinonato d-block complex and its reactivity toward dioxygen, closely associated with a biological system of an oxygen evolving centre of photosystem II.

An IrSi oxide film as a highly active water-oxidation catalyst in acidic media

We report an acid-stable IrSi oxide film made by MOCVD of an Ir^V complex for electrochemical water-oxidation.

A macrocyclic tetraamine bearing four phenol groups: a new class of heptadentate ligands to provide an oxygen-sensitive luminescent Tb(iii) complex with an extendable phenol pendant arm

The potentially N₄O₄-octadentate ligand unprecedentedly coordinates to the Tb³⁺ion in a N₄O₃-heptadentate fashion and provides a highly luminescent and highly oxygen-sensitive terbium(iii) complex.
