This ligand displays both chemical and redox noninnocence, including the generation of a rare, metal-bound aminyl radical. Several four- or five-coordinate Ni(II) complexes of various geometries were obtained, including chloride, phenoxide, and metallacyclic complexes, the latter of which result from ligand activation. Cyclic voltammetry (CV) of the four-coordinate complexes showed reversible oxidation events (E1/2 = ca. –0.5 V vs. Fc0/+) and the oxidation product of the phenoxide complex was fully characterized. The oxidation was determined to be primarily ligand-centered, as supported by electron paramagnetic resonance spectroscopy, X-ray crystallography, and density functional theory (DFT) calculations. More anodic, irreversible oxidation features were also observed for these complexes by CV (Ean = ca. +0.1 V vs. Fc0/+). DFT computations on the second oxidation were consistent with a second ligand-centered process to generate nitrenium-like (R2N+) electronic structures. These studies showcase the versatility of this pincer ligand both by stabilizing complexes of varying geometries and coordination numbers and by providing electrons during oxidation.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 28","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70312","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike typical phase transition materials, zirconia exhibits an unusual thermodynamic relationship in which the metastable tetragonal phase possesses a smaller volume than the thermodynamically stable monoclinic phase. In this study, we investigate the pressure-induced phase transition behavior of tetragonal zirconia nanoparticles under hydrostatic and anisotropic pressure conditions. Tetragonal zirconia nanoparticles were synthesized and subjected to anisotropic and hydrostatic pressure. X-ray diffraction measurements reveal that the tetragonal phase remains largely stable even under hydrostatic pressure up to ~1000 MPa. Conversely, anisotropic pressure readily induces a tetragonal-to-monoclinic transformation. Under strong anisotropic pressure, approximately half of the phase transforms to the monoclinic phase at pressures as low as ~50 MPa, indicating a high sensitivity to nonhydrostatic stress components. This pressure-response behavior is interpreted by considering the isotropic stress generated under hydrostatic pressure and the local strain arising from the inhomogeneous stress distribution under anisotropic loading. These findings indicate that tetragonal zirconia nanoparticles can serve as sensitive probes for detecting nonhydrostatic pressure components in the MPa range, thus providing an approach for evaluating pressure anisotropy under practical pressure environments.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 27","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.70302","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report a surrogate-guided latent-space reinforcement learning workflow for generative ligand design under sparse and heterogeneous extraction-data conditions. A junction-tree variational autoencoder was pretrained on ligand structures extracted from CSD-derived coordination compounds and fine-tuned on literature-reported Am/Eu extractants to construct a chemically valid ligand latent space. A condition-aware XGBoost surrogate model predicted ln(SF) from ligand, solvent, and experimental-condition features and supplied the reward signal for proximal policy optimization (PPO). The surrogate retained useful ranking ability, including under a strict ligand-level split, while PPO enriched multiple regions associated with high surrogate-predicted performance. The generated candidates recapitulated established soft-donor and N-heterocyclic design patterns while suggesting new structural variants in the learned ligand space. This workflow demonstrates how surrogate-guided generative optimization can translate limited Am/Eu extraction data into chemically meaningful ligand-design hypotheses.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 27","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All energy profiles were benchmarked against the well-established trihexylborane/dimethylsulfoxonium methylide (Corey’s ylide) system. Our model set comprises tripropylborane, -alane, and -galane initiators paired with nitrogen- and phosphorus-based methylides. The tripropylborane/trimethylammonium methylide mechanism closely corresponds to the reference pathway, and diazonium methylide in combination with tripropylborane, tripropylalane, or tripropylgalane also reproduces the characteristic features of the established PH reaction pathway, with 1,2-migration barriers ranging from 16.9 to 24.8 kcal mol−1. These results indicate that such initiator/ylide pairs constitute experimentally viable candidates for extending PH chemistry. Across all systems, nitrogen-derived ylides consistently promote PH initiation more efficiently than their phosphorus analogs, primarily due to the lower strain associated with the structural deformation of the ylide fragment and the different rigidity imposed by its substituents. Together, these mechanistic trends provide a coherent picture of initiation in PH and, supported by complementary computational analyses, offer an initial framework that can guide future development of new p-block-based initiator/ylide systems.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"29 27","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrogen evolution reaction (HER) performance of Ru1 and Ru2 was evaluated in alkaline, neutral, and acidic electrolytes. Ru2 exhibited the best activity in 1.0 mol L−1 KOH, with an ECSA of 47.5, η10 of 380 mV, Tafel slope of 375.6 mV dec−1, and turnover frequency (TOF) of 97.7 h−1 at 475.6 mV overpotential. Density functional theory calculations revealed that the DPPPy ligand in Ru2 narrows the gap between the highest occupied molecular orbital (HOMO) and lowest unoccupied orbital (LUMO) (2.90 vs. 3.21 eV), raises the HOMO level (−5.28 vs. −8.22 eV), and increases the positive charge on Ru (+0.173 vs. +0.063), thereby promoting electron transfer and hydride formation.

Under these optimized conditions, the resulting d-CDs exhibited a quantum yield of 23.2%. In a phosphate buffer (pH 7.0), the d-CDs demonstrated specific fluorescence recognition for sulfite ions (SO32−), achieving a quenching efficiency of 64.6%.
