Summary: The treatment of CoCl2 center dot 6H(2)O and tris(pyrazolyl-1-yl)borate tricyanoiron(III) anions at an elevated temperature resulted in two less-common pearl-chain-like compounds. Compound 1 exhibited typical single-chain magnet behavior with an effective energy barrier of 28.0 K, while compound 2 did not show Glauber dynamics despite their similar structures. Changes in the local coordination environments of cobalt ions and cyanide linkages were identified as contributing factors to the significant difference in their magnetic properties.

Summary: Single-molecule magnets (SMMs) offer unmatched information storage density, potential applications in quantum computing and spintronics, and are mainly organometallic lanthanide complexes. However, the challenge lies in surface immobilization due to the sensitivity of magnetic properties to changes in electronic structure. This study successfully identifies siloxides on partially dehydroxylated silica surface as suitable replacements for typical ligand architectures, leading to a significant increase in magnetization relaxation times.

Summary: Two isomeric Co(ii) complexes with the same molecular formula of [Co(napy)(2)(NO3)(2)] (napy = 1,8-naphthyridine) were synthesized and their structures were determined. The complexes exhibit highly irregular six-(1) and seven-coordinate (2) geometries. Magnetic measurements, X-band EPR data, and theoretical calculations were conducted to investigate their properties, revealing field-induced slow magnetic relaxation in both complexes, with 2 attributed to an easy-plane anisotropy.

Summary: This work investigates the dynamic magnetic properties of a complex [(Cp-Ar3)(4)(Dy2Cl4K2)-Cl-III]& BULL;3.5(C7H8) synthesized using a tri-aryl-substituted cyclopentadienyl ligand (Cp-Ar3). The Dy(III)-metallocene weakly couples via K2Cl4 and exhibits slow relaxation of magnetization below 14.5 K under zero applied dc field through KD3 energy levels with an energy barrier of 136.9/133.7 cm(-1) at the Dy sites. The coordination of two chloride ions at each Dy centre leads to geometrical distortion and reduction of the single-ion axial anisotropy energy barrier.

Summary: Recent progress has been made in using single molecule fluorescence microscopy imaging to study nanoconfinement in porous materials, revealing static and dynamic heterogeneities between seemingly equal molecules by removing ensemble averaging effects. These studies allow for the investigation of various physicochemical processes at nanometer spatial resolution and provide the ability to quantitatively measure the inhomogeneities of nanoconfinement effects.

Summary: By using ultrahigh vacuum tip-enhanced Raman spectroscopy (UHV-TERS), single oxygen adatoms on a boron monolayer (borophene) can be identified and mapped with a spatial resolution of approximately 4.8 angstrom and single bond sensitivity. This technique enables the atomically defined, chemically homogeneous, and thermally reversible oxidation of borophene via atomic oxygen in UHV. Additionally, it reveals the propensity of borophene towards molecular oxygen activation at room temperature and phase-dependent chemical properties. Overall, this work demonstrates the powerful utility of UHV-TERS in probing the local chemistry of surface adsorbates in the atomic regime and has important applications in heterogeneous catalysis, on-surface molecular engineering, and low-dimensional materials.

Summary: Three sandwich-like [Ln2Fe2(B-alpha-FeW9O34)2]10- clusters (Ln2Fe4, Ln = Dy (1), Ho (2), and Y (3)) were synthesized by reacting Na9[B-alpha-SbW9O33], Ln2O3, FeCl3 center dot 6H2O, and KH2PO4. The [B-alpha-FeW9O34]11- units were formed via the in situ conversion of lacunary polyoxometalates (POM) [B-alpha-SbW9O33]9- and the Ln3+ ions were generated from the slow dissolution of Ln2O3, both of which play important roles in the synthesis of Ln2Fe4. Ln2Fe4 is the first 3d-4f cluster assembled from d-metal heteroatom-containing POM. The Dy2Fe4 cluster exhibits single-molecule magnet properties with an 80 K energy barrier in an optimal DC field. Cyclic voltammetry tests and controlled-potential coulometry experiments show that the polyoxometalate Fe heteroatom in clusters 1-3 is also electrochemically active.

Summary: The study reports on an enantiopure coordination polymer involving a BINOL-derived bisphosphate ligand and demonstrates the formation of a mononuclear species in solution. The electronic circular dichroism signals were enhanced after metal coordination, and both polymeric and mononuclear structures exhibited field-induced Single-Molecule Magnet behavior. The HOMO -> LUMO transition of the ligand induced classical Dy(iii) emission at 77 K, correlating with the magnetic properties of the assembly.

Summary: The extreme sensitivity of trivalent lanthanide ions to crystal field variations leads to the emergence of single-molecule magnetic switching under various stimuli. Pressure can be used as an external stimulus to finely tune the magnetic modulation of single-molecule magnets, instead of traditional methods like light irradiation or chemical reactions. Experimental investigation of a well-known single-molecule magnet under high applied pressures demonstrated reversible piezo-chromic properties and pressure modulation of slow magnetic relaxation behavior, which were supported by ab initio calculations. The magnetic study of a diluted sample indicated that variations in the electronic structure mainly have an intermolecular origin with weak intramolecular contribution.

Summary: In this study, the authors characterized the structure and magnetic properties of four distorted tetrahedral homoleptic Co(II) complexes. These complexes exhibit Single-Ion Magnet (SIM) behavior, with large and negative magnetic anisotropy. Theoretical calculations showed that the axial anisotropy is mainly caused by electronic transitions, and the structural distortion was also explained and reproduced by calculations.

Summary: In this work, a strategy of electrocrystallization was used to synthesize a metallocycle with intrinsic electron conductivity. The metallocycle units formed one-dimensional helical pi-stacked columns and pore channels through a densely packed sequence, maintaining their stability during the liberation of H2O molecules. The NDI cores were partially reduced to form radicals, resulting in a higher room-temperature conductivity compared to other NDI-based conductors.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
