While most examples employ s-block metal amides, Co(TMP)2 has also emerged as a powerful metalating reagent for the cobaltation of pyridines and fluoroarenes. Herein, we investigate the ability of this Co(II) metal amide to undergo insertion reactions into its Co–N bonds by assessing its reactivity toward a range of heterocumulenes and unsaturated organic molecules. Excellent stoichiometric control was achieved in reactions toward phenyl isocyanate, diphenyl ketene, and carbon dioxide, where one or two of the TMP groups can undergo insertion. Contrastingly, extending these studies to 4-methylacetophenone revealed the preference of this metal amide to act as a base to form the relevant enolate complex. The reactivity of Co(TMP)2 toward phenyl isocyanate, benzonitrile, and 4-methylacetophenone was contrasted with that of the classical Co(II) amide Co(HMDS)2, which shows, in most cases, a diminished nucleophilic power and lower selectivity.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"75 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical analysis reveals that RbOn– and CsOn– have similar structures. They can be described as polyoxide units electrostatically stabilized by alkali metal cations, with structural motifs that follow systematic trends: [O2]−–M+–[O2]− (n = 4), [O3]−–M+–[O2]− (n = 5), [O2]−–M+–[O2]2– (n = 6), and [O3]−–M+–[O2]2– (n = 7). These results confirm that electrostatic interactions dominate the bonding between alkali metal cations and oxygen-rich units, and the polarization effects become more pronounced with the increase of cluster size.

The process involves an electrochemically driven cyanide-to-bipyridine ligand exchange directly on a Nafion/carbon soot (Nf-CS)-modified electrode, thereby avoiding conventional multistep solution-phase synthesis. Cyclic voltammetry, Raman spectroscopy, Fourier transform infrared spectroscopy, UV–vis spectroscopy, high-resolution mass spectrometry, and electrochemical quartz crystal microbalance measurements collectively confirm the formation of surface-confined [Fe(bpy)3]2+ and provide evidence for transient Fe2+/Fe3+ intermediates during CSR. A selective Prussian Blue test further confirms CN– release, supporting the proposed ligand-exchange mechanism. The resulting GCE/Nf-CS@[Fe(bpy)3]2+ electrode exhibits remarkable electrocatalytic activity toward nitrite oxidation, with a sensitivity of 150 μA mM–1, approximately 10-fold higher than that of chemically synthesized [Fe(bpy)3]2+-based electrodes. The electrode also demonstrates a low overpotential, excellent operational stability, and negligible fouling. Coupling with batch injection analysis enables rapid, selective, and reproducible nitrite determination in serum, urine, saliva, spinach, and wastewater samples, with recoveries of 98–101%.

In contrast, (H2CDA)SbI5 does not show any detectable transition within the studied temperature range. The optical band gaps are in the 2.0–2.3 eV range, with (H2CDA)SbI5 exhibiting a significantly wider gap compared to the other two analogs, attributed to pronounced distortion of the Sb–I framework, particularly increased Sb–I–Sb tilting. Additionally, (H2BDA)SbI5 exhibits a broad, Stokes-shifted emission centered at 720 nm and extending to 1200 nm.

Herein, two antimony tellurite-based compounds, centrosymmetric (CS) Sb2O(TeO3)2 and noncentrosymmetric (NCS) SbTeO3F, were synthesized and compared to investigate fluorination-associated structural and optical regulation. Sb2O(TeO3)2 crystallizes in the CS space group P1̅ and features a layered framework of [SbO4], [SbO5], and [TeO3] units connected through Sb–O–Te linkages. In contrast, SbTeO3F adopts the NCS space group P212121, in which terminal Sb–F coordination accompanies changes in Sb coordination and Sb–Te–O framework connectivity. SbTeO3F exhibits improved UV transparency, shifting the absorption edge from 394 to 304 nm and increasing the experimental band gap from 3.15 to 4.08 eV. Both compounds retain large birefringence values of 0.29 and 0.30 at 546 nm, respectively. SbTeO3F also exhibits a measurable powder second-harmonic generation (SHG) response of approximately 0.6 times that of potassium dihydrogen phosphate (KDP, KH2PO4). First-principles calculations suggest that the band gap widening is related to modified band-edge electronic states, whereas large birefringence is associated with anisotropic lone-pair-active Sb3+ and Te4+ units. These findings highlight the potential of fluorination-associated structural regulation for improving UV transparency while preserving large birefringence in antimony tellurite-based crystals.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"20 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study defines two pivotal criteria for eligible parent precursors, verifying colloidal monometallic Pt, Au, and Pd NPs, as well as their bimetallic derivatives, as ideal candidates. The differential competency and rich diversity of parent precursors allow us to design a variety of rational synthetic routes, which enables that the versatile synthesis of MMANPs, including over 200 monodisperse Pt-based ternary-to-senary alloy nanocubes, to be theoretically achieved (the constituent metals studied include Pt, Au, Pd, Fe, Co, Ni, Rh, Ag, Cu, Mn, and Sn).

Remarkably, complex 1 undergoes ultrasound-induced supramolecular self-assembly in water to form a robust Au(I) hydrometallogel (1-hyd), whereas 2 lacks the capacity to gelate due to coordination-induced suppression of intermolecular hydrogen bonding. The hydrometallogel acts as both a soft template and an in situ gold precursor, enabling the formation of densely packed, belt-like assemblies of plasmonic Au nanoparticles (1-hyd-Au NPs) upon mild and short thermal treatment. These anisotropic nanoarrays display strong interparticle coupling, yielding a broad, red-shifted localized surface plasmon resonance (LSPR) absorption centered at ca. 650 nm with substantial NIR absorption. Under 808 nm excitation, the system exhibits efficient photothermal conversion accompanied by the generation of localized plasmonic hot spots. Exploiting this dual activation mode, 1-hyd-Au NPs photocatalyse the methanolysis of ammonia-borane, delivering significantly enhanced H2 release relative to purely thermal conditions.
