A facile synthesis of the [ReF6 ](2-) ion and its use as a building block to synthesize magnetic systems are reported. Using dc ac susceptibility measurements, INS EPR spectroscopies, properties isolated unit in (PPh4 )2 ]⋅2 H2 O (1) have been fully studied including slow relaxation magnetization observed below ca. 4 K. This dynamic is preserved for one-dimensional coordination polymer [Zn(viz)4 (ReF6 )]∞ (2, viz=1-vinylimidazole), demonstrating irrelevance low symmetry such dynamics with...
Abstract The tailored chemical synthesis of binary and ternary alloy nanoparticles with a uniform elemental composition is presented. Their dual use as magnetic susceptors for induction heating catalytic agent steam reforming methane to produce hydrogen at temperatures near above 800 °C demonstrated. performance two chemically synthesized samples CoNi Cu ⊂ are compared held against traditional Ni‐based catalyst. structural, magnetic, properties the were characterized by X‐ray diffraction,...

Exploitation of HSAB preferences allows for high-yield, one-pot syntheses lanthanide complexes chelated by two Pd or Pt metalloligands, [MII(SAc)4]2- (SAc- = thioacetate, M Pd, Pt). The resulting with 8 oxygen donors surrounding the lanthanides can be isolated in crystallographically tetragonal environments as either [NEt4]+ (space group: P4/mcc) [PPh4]+ P4/n) salts. In case Pt, complete series has been structurally characterized salts (except Ln Pm), while have Gd-Er, Y. For selected both...
Induction heating by magnetic hysteresis of nanoparticles inside chemical reactors is an interesting approach for direct and electrified high-temperature endothermic catalytic reactions. Here, we show how it possible to tune the induction steam methane reforming use alumina-supported CoxNi(100–x) with well-defined alloy compositions from x = 20 90. The ∼30 nm Co–Ni particles function both as a catalyst susceptor. We find that increases increasing Ni content at lower temperatures smaller...
Simultaneous retention of SMM behaviour and optical activity is demonstrated upon surface deposition for a chiral SMM.
Abstract A facile synthesis of the [ReF 6 ] 2− ion and its use as a building block to synthesize magnetic systems are reported.

β-Diketonates, such as acetylacetonate, are amongst the most common bidentate ligands towards elements across entire periodic table and considered wholly redox-inactive in their complexes. Herein we show that complexation of 1,1,1,5,5,5-hexafluoroacetylacetonate (hfac- ) to CrII spontaneously affords CrIII a reduced β-diketonate radical ligand scaffold, evidenced by crystallographic analysis, magnetic measurements, optical spectroscopy, reactivity studies, DFT calculations. The possibility...
Tailoring the chemical surroundings of chromium(<sc>ii</sc>) allows reversible electron-transfer to ubiquitous, purportedly redox-inactive acetylacetonate.
Achieving control over coordination geometries in lanthanide complexes remains a challenge to the chemist. This is particularly case field of molecule-based magnetism, where barriers for magnetic relaxation processes as well tunneling pathways are strongly influenced by geometry. Addressing design 4f-element environments, ubiquitous Ln(hfac)3 moieties have been shown be applicable Lewis acids coordinating transition metal acetylacetonates facially leading simple, chiral lanthanide–transition...
Ein robuster Baustein für magnetische Systeme resultierte aus einer neuen, effizienten Synthese des [ReF6]2−-Ions. K. S. Pedersen, R. Clérac, J. Bendix und Mitarbeiter berichten in ihrer Zuschrift auf 1375 ff., dass nach Einbau [ReF6]2− ein NiII-ReIV-1D-Koordinationspolymer das Fluorid signifikante Kopplungen vermittelt. Die ferromagnetische Ni-F-Re-Wechselwirkung (+11 cm−1) stellt die verwandten Cyanid-verbrückten Systemen beobachteten Werte den Schatten.
