A Cyclic {NiII8DyIII4} Cluster Where the DyIII Moments Are Organized by the Transition Metal Spins

Chemistry – A European Journal, EarlyView.
The synthesis, structural characterisation, and magnetic properties of a cyclic Ni8Dy4 coordination cluster are reported. Ab initio CASSCF and DFT calculations help rationalize the shape of the microSQUID hysteresis and the competing magnetic interactions within the compound. ABSTRACT A series of [Ni8Ln4(CO3)4(L)8(NO3)2(H2O)8 (MeOH)4](NO3)2 (Ln = Dy (1)

Redox‐Switchable Optical and Magnetic Properties in a Self‐Assembled Hexanuclear Ni(II) Double‐Decker Complex

Chemistry – A European Journal, EarlyView.
A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

Scaling Up Molecular Electron Spin Qubits Around a Core‐Shell Quantum Dot

Chemistry – A European Journal, EarlyView.
Making assemblies of molecular nanomagnet (MNM) qubits is an essential step toward scalable quantum devices. Here, SH‐functionalized {Cr7Ni} antiferromagnetic rings with ability as MNM qubits were successfully grafted to the surface of fluorescent CdSe/ZnS quantum dots (QD).

Large Magnetocaloric Effect in a Ferromagnetically Coupled [Mn3Gd] Complex With a Spin Ground State of S = 11

Chemistry – A European Journal, EarlyView.
Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(

Direct Observation of a Hydrogen‐Bonding Assisted Quasi‐Reversible Superoxo/Peroxo Interconversion in a Heme Model

Chemistry – A European Journal, EarlyView.
First direct observation of a quasi‐reversible superoxo (FeIII─O2˙ˉ)/peroxo (FeIII─O22ˉ) redox couple in a heme model complex, featuring a biologically relevant low‐spin ferric end‐on peroxo species stabilized by second‐sphere hydrogen bonding. These findings highlight the key role of second‐sphere interactions in modulating O2 activation pathways ...

A Low‐Oxidation‐State Mechanism for O─O Bond Formation in Photosystem II via Oxo–Hydroxyl Radical Coupling

Chemistry – A European Journal, EarlyView.
An oxo–hydroxyl radical coupling mechanism is identified for O─O bond formation in Photosystem II within the low‐oxidation‐state paradigm. Ca‐bound W3 forms Ox in the S4 state and subsequently couples with O5. The resulting hydroperoxide intermediate provides a mechanistic explanation for the poor resolution of Ox in XFEL structures.
