Summary: The elusive octahedral hexapalladium Pd6(mu 3-CO)4(PEt3)6 (1) was obtained by reaction and was found to have a pseudo-Td octahedral structure with the highest ideal symmetry among the characterized octahedral-based CO/PR3-ligated homopalladium Pdn clusters. Each Pd atom is coordinated to a PEt3 ligand and the nonadjacent triangular Pd3 face is capped by a triply bridging mu 3-CO ligand. The cluster has a total of 80 cluster valence electrons (CVEs), the lowest reported for octahedral-based metal polyhedra.

Summary: The 2,4,6-OMe-TCF dye with aggregation-induced emission (AIE) phenomenon is studied for laser light generation. Strong light amplification is possible only for concentrated solutions near saturation level, indicating the essential role of aggregation in enhancing light emission. Additionally, powdered form of the dye also exhibits lasing, but with a red-shifted gain profile. The dye can be used both in liquid solution and as dopant for polymeric matrices, making it suitable for soft and elastic materials in printed optoelectronics.

Summary: Heavy element compounds with high symmetries often have both spin-orbit coupling and vibronic coupling, particularly in systems with tetrahedral and octahedral symmetries. To accurately describe these interactions, high quality spin-orbit vibronic Hamiltonian operators are needed. This study presents a unified Hamiltonian formalism for spin-orbit vibronic interactions in all tetrahedral and octahedral symmetries, generating Hamiltonian expansion formulas of arbitrarily high order.

Summary: When atoms are placed into liquids, their optical spectral lines become broadened, making it difficult to perform high-resolution spectroscopy. However, researchers have discovered that when an exotic helium atom with an antiproton is embedded into superfluid helium, its visible-wavelength spectral line retains a sub-gigahertz linewidth. This opens up possibilities for studying other helium atoms containing antinuclei, as well as mesons and hyperons formed in superfluid helium, and determining the masses of particles.

Summary: The nuclear Overhauser effect (NOE) is a result of cross-relaxation between nuclear spins mediated by dipolar coupling, becoming increasingly important in determining through-space atom proximity relationships within molecules. The efficiency of NOE depends on the molecular rotational correlation time, and increasing solution viscosity can reveal otherwise unobservable NOEs.

Summary: The research conducted the first-ever attempt at using CoGA metal-organic framework (MOF) in an analytical method for extracting and preconcentrating fungicides and herbicides from apple juice samples. The method showcased several advantages such as no organic solvent usage, gallic acid as the ligand, cobalt as the cationic center, no high temperatures or long reaction times during synthesis, and one-pot synthesis feature. The approach also featured a green one-step extraction process using a small amount of MOF and a low volume of desorption solvent, and it achieved high extraction recoveries, low limits of detection and quantification, and low relative standard deviations for intra-day precisions.

Summary: New nanocomposite materials with UV-NIR blocking properties and hues ranging from green to brown were prepared by integrating inorganic tantalum octahedral cluster building blocks prepared via solid-state chemistry in a PMMA matrix. The oxidation state of the Ta-6 cluster inorganic building blocks can be controlled to tune the optical and blocking properties of the composite. The synthesis involves the solid-state chemical reaction of ternary halide K-4[{Ta6Br12i}Br-6(a)] and the replacement of potassium cations with functional organic cations (Kat(+)) bearing a methacrylate function.

Summary: This study investigates the effect of metal/ligand on the photoinduced conductivity properties of two types of cluster core building blocks, {Re6S8i} and {Re6Se8i}, using a comprehensive range of characterization techniques. The composition of {Re(6)Q(8)(i)}-based films (Q = S or Se) significantly affects their optical and electronic properties. By increasing the interactions between the cluster building blocks through heating, the electronic properties can be enhanced. The design of mixed {Re(6)Q(8)(i)}-based photoelectrodes combining n-{Re6S8i} and p-{Re6Se8i} cluster core-based building blocks allows for the optimization of photocurrents, making them attractive for solar cell applications.

Summary: Two neutral copper(I) halide complexes were prepared using benzoylthiourea (BTU) ligand in ethanol. These complexes displayed interesting properties such as 2D supramolecular structures, liquid crystalline behavior, emission, and 1D ionic conduction. The chemical structure was determined through various spectroscopic techniques while the mesomorphic behavior was analyzed using DSC, POM, and XRD. The complexes exhibited a hexagonal columnar mesophase over a wide temperature range and showed solid-state emission with high quantum yields. The liquid crystal phases also facilitated anhydrous proton conduction provided by hydrogen-bonding networks.

Summary: In this study, two inorganic polymeric cluster compounds, Cs[Mn(salen)](3)[{Mo6Br6Se2}(CN)(6)] (1) and (H3O)(TBA)[Mn(salen)](2)[{Mo6Br6Se2}(CN)(6)] (2), were synthesized and their structures were characterized. The compounds were built-up using [{Mo6Br6Se2}(CN)(6)](4-) building blocks and Mn(salen)(+) complexes. The counter cations (Cs+ or TBA(+)) played a crucial role in controlling the interactions between the building blocks and the Mn(salen)(+) groups. Compound 1 was obtained by diffusion of K2Cs2[{Mo6Br6Se2}(CN)(6)] cluster compound into a solution of Mn(salen)ClO4, while compound 2 was obtained by addition of tetrabutylammonium bromide into the solution of Mn(salen)ClO4. The structures of 1 and 2 were discussed and compared with relevant examples from literature.

Summary: A series of new cluster compounds containing {Re4Mo2S8} and {Re3Mo3S8} cores have been synthesized and studied. The clusters with different Re/Mo ratios were obtained as separate compounds, allowing for characterization of their spectroscopic and electrochemical properties. The geometry of the clusters was determined using X-ray diffraction analysis, XAS, and quantum chemical DFT calculations. The results showed that the new clusters exhibit similar properties to clusters based on {Re4Mo2Se8} and {Re3Mo3Se8} cores, including the number and position of electrochemical transitions, electronic structure, and changes in geometry upon charge variation.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
