The reductive addition of small molecules to low-valent main-group centers has recently started to emerge, yet their redox labeling is often inferred from qualitative electronegativity arguments and partial-charge trends. Here, we use a recent representative example, i.e., Zn-Zn bond cleavage by Si^II and Al^I main-group carbene analogues as a motivating case study and place i…

By incorporating electroactive triphenylamine units into a hexacarboxylate linker, two zinc-based metal-organic frameworks with 3,24-connected <i>rht</i> net were constructed, demonstrating unique anion-dependent intermolecular charge/electron and energy transfer. The crystals of <b>Zn-MOF-1</b> incorporating nitrate anions within the framework are red and do not show fluorescence at all, while <…

Boron materials, particularly boron allotropes, have emerged as appealing potential hard and superconducting species for practical applications due to their abundant building blocks, robust chemical bonding patterns, and peculiar electron structures induced by an electron deficiency. However, the boron isomers that simultaneously exhibit superhardness above 40 GPa and superior superconductivity h…

A novel in situ impregnation conversion method was proposed for constructing hierarchical porous metal-orgainc framework (MOF) films. This approach relies on the conversion of a Cu(OH)₂@PVA precursor film into a Cu-MOF film via a controlled in situ growth process. The resulting MOF films exhibited high accessibility to active sites and robust free-standing properties.

Two-coordinate plumbyliumylidene ions constitute a rare class of highly electron-deficient cationic Pb(II) species. Herein, we report the synthesis and structural characterization of iminophosphonamido-supported plumbyliumylidene ions bearing two different borate counteranions, {B[(4-^<i>t</i>BuMe₂Si)C₆F₄]₄}^- and [B(C₆F<s…

Rare-earth materials are commonly described as "industrial vitamins" since they are mainly employed as structural or electronic modifiers rather than as direct catalytic centers. This is because their highly shielded 4f electrons prevent them from effectively participating in interfacial charge transfer. In this work, we break this long-standing limitation by engineering atomically dispersed lant…

Birefringent crystals can manipulate the phase and polarization of light, and are therefore widely used as key components in various optical devices. In this study, the hydrogen-bonding interactions between the [C₈H₆FN₂O]⁺ donor and the anionic acceptors, namely [SiF₆]^2- and Cl^-, were utilized to achieve a high degree of…

This study utilized the magnetic separation of steel tailings as raw material, employing ammonium chloride as the chlorinating agent to extract valuable manganese elements from steel slag through chlorination roasting. Initially, the feasibility of manganese extraction from steel slag via chlorination was analyzed based on thermodynamic calculations. Subsequently, single-factor experiments, in co…

Manganese-based hybrid metal halides are attractive for scintillator applications due to their high emission efficiency and good stability. However, most high-performance manganese scintillators rely on bulky and complex organic cations as A-site components, which reduce the lattice density and compromise X-ray absorption. To address this issue, we employed a small piperidinium cation (C<sub>5</s…

The complexation of plutonium(IV) by acetate anions as [Pu(AcO)<i>_n</i>]^4-<i>n</i> species does not exist under the experimental conditions used in the literature and in our experiments. Using capillary electrophoresis (CE) coupled with ICP-MS, we discovered that in the Pu(IV)/acetate/water system, two distinct kinetics coexisted for which it was possible to determine the as…

Five new bis(ZnDy) complexes with the general formula [Zn₂(μ-H₂L)₂(μ-dicarb)Dy₂(L')₂(L'')₂]X₂·solv were synthesized using Mannich bis(compartmental) ligand H₄L (highly phenoxido-containing macrocycle). Tetrafluorosuccinate (<b>1</b>, <b>3</b>) and succinate (<b>2</b>, <b>4</b>, <b>5</b>) were used as dicarboxy…

In contemporary society, heavy metal ions have posed significant threats to water systems and human health, for which timely and accurate detection is of much significance. In this work, a new metal-organic framework, CUST-1022, [Cd(H₂BPDC)(phen)]CH₃OH was synthesized via the solvothermal method. Due to the existence of uncoordinated carboxyl sites in CUST-1022, Eu<sup>3+</s…

Chiral inorganic crystals, particularly semiconductors with Weyl points near the band edges or semimetals hosting Weyl points at the Fermi level, have attracted considerable interest; yet, they remain scarce in existing materials databases. This study presents a prediction pathway by combining universal machine-learning interatomic potentials (uMLIPs) for high-throughput structure optimization wi…
