Summary: Four acyl-hydrazones and two hydrazones were synthesized and their structures were determined by X-ray diffraction. Twelve rhenium(I) complexes were obtained and their structures were determined. The coordination geometry around rhenium(I) can be described as octahedral, and the carbonyl group of acyl-hydrazone ligands does not participate in coordination.

Summary: Cluster complexes have recently been designed with ligand scaffolds specifically tailored to support multinuclear transition metal cores in order to facilitate cooperative small molecule activation. The incorporation of geometric flexibility and redox-active ligands in the ligand design allows for unique small molecule activation modes, providing significant analogies to heterogeneous and metalloenzyme catalysts.

Summary: Electrospray ionization mass spectrometry (ESI-MS) is a powerful label-free assay for detecting noncovalent biomolecular complexes and quantifying binding thermochemistry. However, the assumption that the ion signals of free and bound species in ESI-MS measurements can quantitatively reflect their relative concentrations is only valid when their response factors are similar.

Summary: In this study, coordination geometry was used as a new tool to regulate non-covalent interactions, photophysical properties, and energy landscape of supramolecular polymers. By designing two self-assembled Pt(ii) complexes with different coordination and molecular geometry, it was possible to achieve fine control of PtPt distances and tunable luminescent properties. This highlights the importance of coordination geometry in the development of functional supramolecular materials.

Summary: In this study, the uniqueness and importance of F430 in methane production were computationally explored. It was found that F430 has significant advantages in catalytic performance compared to four identified biosynthetic precursors. Contrary to expectations, the increase in reduction potential along the biosynthetic pathway of F430 was outweighed by the strengthening of the Ni-S bond, resulting in a significantly reduced rate-determining barrier. The transition state showed higher reactivity of the CH3 fragment compared to its biosynthetic ancestors, likely preventing the formation of deleterious radical intermediates. This study provides a plausible understanding of how the evolutionary driving force shaped the catalytic proficiency of F430 in CH4 formation.

Summary: The assembly of highly ordered nanomaterials through charge transfer interactions is achieved in this study, where pyrene and naphthalenediimide functionalized oligodimethylsiloxanes are synthesized and co-assembled in bulk. By tuning the donor-acceptor interactions through connecting pyrene and NDI to the same oligomer or to two separate oligomers, different types of donor-acceptor molecules are obtained. The discreet length of the oligodimethylsiloxane units plays a crucial role in the formation of liquid crystalline materials and CT dimers.

Summary: This study investigates a novel molecular tetramer compound composed of triangular CuV2 fragments and reveals drastically different coupling strengths of superexchange Cu-V interactions in the presence of similar bond angles. By analyzing the magnetic orbitals and crystal field, the origin of the disparity is identified and compared with a similar chain compound. The findings highlight the possibility of observing fundamentally different magnetic couplings between magnetic ions in a single spin motif.

Summary: In this study, the coordination properties of ligands were investigated by modifying their side chain structure. The results showed that the length of the aliphatic linker, isomers of the amide group, and the type of chiral terminal group all had an impact on the coordination properties. Additionally, DFT calculations provided insights into the stability of isomers and the potential hydrogen bonding between ligands in a ML2 complex.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

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.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
