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: 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) are molecules that exhibit slow relaxation of magnetization and have potential applications in information storage and quantum computing. To make them practical, high blocking temperature and effective energy for magnetization reversal are required. Enhancing magnetic anisotropy can reduce quantum tunneling of magnetization. Among transition metal ions, Co(II) is a superior choice for designing single-ion magnets.

Summary: Two mononuclear complexes, [(tfnb)(3)Ln(phen)] (Ln = Tb or Dy, tfnb = 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione, phen = 1,10-phenanthroline), were structurally determined using single crystal X-ray diffraction. The crystallographic data showed that the two complexes have isostructural trigonal dodecahedral geometries. The dysprosium complex exhibited slow relaxation of magnetization without a dc field, with an effective barrier U-eff of 193 K obtained by considering QTM, Raman, and Orbach processes for energy barrier fitting. The calculated magnetic easy axis using an electrostatic model aligned with the direction of the two tfnb(-) ligands in the trans position.

Summary: In this study, a hexanuclear compound with a rhombic core structure {(Fe2FeI2)-Fe-III-I-I} was synthesized. The compound exhibited thermally-induced spin transition with thermal hysteresis. The deformation of the FeII centers during the spin transition process led to colossal anisotropic thermal expansion, which was spread over the entire crystal through molecular rearrangements. This research provides a rational strategy for achieving colossal anisotropic thermal expansion and shape memory effects through tuning magnetic bistability.

Summary: Three stable supramolecular radicals with ferroelectric phase transitions and bistability in dielectric property and second-harmonic generation effect were synthesized and characterized. The ferroelectric transition and bistable properties are generated from a net polar crystal structure and a distinctive symmetric scissoring motion of the radicals, respectively. These results pave the way for designing bistable optoelectronic radical materials with magnetic bistability in the future.

Summary: The preparation of two cyanide-bridged [Fe4Co4] cube complexes using different functionalized ligands was studied. The first complex showed an incomplete metal-to-metal electron transfer behavior at around 220 K, while the second complex exhibited a complete and abrupt transfer at 232 K. Both complexes demonstrated a long-lived photo-induced metastable state. The crystallographic study revealed that the incomplete transition in the first complex was likely due to the competition between elastic interactions and alkynyl-alkynyl & CH-alkynyl interactions, which were eliminated in the second complex due to partial substitution by the alcohol-functionalized ligand. The introduction of chemically distinguishable cobalt centers did not result in a two-step transition in the second complex, possibly due to strong ferroelastic intramolecular interaction through the cyanide bridges.

Summary: In this study, a novel gold(I) bifluoride complex, LAuHF2, supported by a sterically bulky ligand (L, (t)BuXantphos), showed exceptional reactivity towards hydrodefluorination (HDF) and hydrosilylation of CO2 in the presence of hydrosilanes. Compared to the LAuCl counterpart, the LAuHF2 complex exhibited significantly higher turnover frequency in HDF and hydrosilylation of CO2. Further experimental and computational studies revealed the critical role of non-coordinated fluoride in silane activation, leading to the generation of an active gold hydride intermediate for catalytic activities. This work demonstrates the importance of counterion effect in gold catalysis and provides new insights for the design of metal catalysts for small molecule activation.

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.
