Summary: Divalent lanthanide organometallics are highly reducing compounds known for single electron transfer reactivity and small molecule activation. This study presents a rare organometallic sandwich compound of divalent thulium with the cyclooctatetraenyl ligand, introducing it as an additional strategy for designing high-performing Single Molecule Magnets. The first divalent thulium sandwich complex with f(13) configuration behaves as a single-molecule magnet even in the absence of a DC field.

Summary: Incorporating robust polyoxometalates to Mn-4 cubanes improves their stability and aqueous solubility, providing a platform for deposition onto selected surfaces during device fabrication. The replacement of terminal carboxylate ligands with inorganic phosphate/polyphosphate groups leads to oligomeric aggregates of Mn-4 clusters. The introduction of inorganic phosphate bridges does not alter the ground state of individual Mn-4 clusters, but leads to different magnetic behaviors primarily due to intercluster interactions.

Summary: The first germole-ligated single-molecule magnets were reported, where contrasting properties were found for the near-linear sandwich complexes [(η^8-COT)Ln(η^5-Cp-Ge)^-], with Ln = Dy or Er. While 1(Er) has an energy barrier of 120(1) cm^-1 in zero applied field and open hysteresis loops up to 10 K, the relaxation in 1(Dy) is characterized by quantum tunneling within the ground state.

Summary: Using a novel tricompartmental hydrazone ligand, a set of trinuclear Dy-3 complexes with different anions (Cl-, Br-, or ClO4-) and co-ligands were isolated and characterized. The magnetic properties of these complexes vary due to structural disorder and different relaxation processes, with Dy-3 center dot ClO4 showing the most robust magnetic behavior. The magneto-structural relationships were analyzed and rationalized using CASSCF/RASSI-SO calculations.

Summary: A series of four new Dy-12 dodecanuclear clusters based on azobenzene derivative ligands of salicylic acid have been synthesized and characterized. The formation of similar metallic cluster nodes in all obtained clusters has been revealed. Different porous 3D molecular networks and grids have been observed in different compounds. Three of the clusters exhibit a slow magnetic relaxation effect and one compound shows a decrease in the magnetic anisotropy energy barrier after UV irradiation, indicating the potential control over magnetic properties by external stimulus.

Summary: Diiron mu-aminocarbyne complexes can be synthesized by reacting sodium cyanate and tetrabutylammonium thiocyanate with pre-prepared diiron aminocarbyne complexes, yielding different substituted diiron cyanide complexes with yields of 67-81%, through substitution of the acetonitrile ligand. When reacted with potassium selenocyanate at reflux temperature, cyanide complexes can be obtained with yields of 45-67%. When reacted at room temperature in acetone, a small amount of potassium selenocyanate complexes can be obtained. All products were fully characterized and the chiral structure was determined by single crystal X-ray diffraction. DFT calculations shed light on the coordination mode and stability of the {NCSe-} fragment.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
