The molecular structure of 4 a–f, 4 h and 4 i in the solid state was confirmed by single-crystal X-ray diffraction studies. All eight crystal structures are centrosymmetric, with the metal positioned in a slightly distorted square plane. Intermolecular non-covalent interactions such as C−H⋅⋅⋅Pd, Cl⋅⋅⋅Cl, Cl⋅⋅ π, C−H⋅⋅⋅Cl, Cl⋅⋅⋅O, C−H⋅⋅ π, and π⋅⋅⋅π play crucial roles in the formation of the supramolecular structures. The crystal structures of 4 b, 4 c, and 4 e revealed unique intermolecular C−H⋅⋅⋅Pd anagostic interactions between the hydrogen atom on the substituted ligand and the palladium centers, which enable the formation of 1-D polymeric chains. The intermolecular non-covalent interactions were analyzed using Hirshfeld surface. The proportional contributions of each individual atom to the formation of these non-covalent interactions are shown in the 2D fingerprint plots. Furthermore, density functional theory (DFT) has been used to compute the energetic estimation of non-covalent interactions in 4 b, 4 c and 4 e.

In a CH2Cl2–H2O mixed solvent, complexes 1 and 2 can be interconverted upon alternately adding AgPF6 and NaCl. Complex 3 can dissociate into complex 2 in solution. These complexes reveal different luminescence. In deaerated acetone, complex 1 is non-luminescent, while 2 show green luminescence with main emission bands at 511 and 534 nm. Complexes 1 and 2 in solid state show similar green luminescence, but significant differences in quantum yield, Φ=7.4 % for 1, and Φ=17.6 % for 2.

Herein, we utilize a half-sandwich type of mononuclear iron complex as the reaction precursor to construct two novel thiolate-bridged diiron complexes featuring the benzimidazole moiety through the oxidative dimerization strategy. X-ray diffraction analysis reveals the two thiolate ligands containing the benzimidazole group in a syn arrangement bridge the two iron centers through the sulfur and nitrogen atoms. Furthermore, Mössbauer spectroscopy and computational studies suggest two complexes both possess two low-spin FeIII ions, but adopt different magnetic couplings to give different electronic structures.

However, research on the optoelectronic properties of these materials is still relatively limited. This study presents the crystal structure and optoelectronic properties of Cs₂FeCl₅⋅H₂O erythrosiderite halide. The results show that Cs₂FeCl₅⋅H₂O is an orange-red needle-like crystal, with its crystal system and space group belonging to the orthorhombic system and Cmcm(63), respectively. Photodetectors made from Cs₂FeCl₅⋅H₂O exhibit stable photocurrent responses in the visible light range (from 397 to 564 nm). Under conditions of a light intensity of 30 W/m2 at 397 nm with a bias voltage of 4.5 V, the responsivity of Cs₂FeCl₅⋅H₂O is 8.41 mA/W, and the detectivity is 4.43 × 106 Jones. There is a strong linear relationship between the net photocurrent density of Cs₂FeCl₅⋅H₂O and light intensity, as well as a strong linear relationship between responsivity and voltage, with R2=0.96. Thus, Cs₂FeCl₅⋅H₂O has excellent optoelectronic performance and is a promising compound for optoelectronic applications.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431103","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}

In the work we have studied the kinetics and mechanisms of the oxidation of ammonia by ferrate(VI) (FeO42–), a well-defined metal oxo species. The kinetics was investigated over a pH range of 7.5 to 10, the rate-law is rate=k2[ferrate][ammonia]. k2 decrease with increasing pH, the results indicated that at pH 7.5 the reacting species are HFeO4– and NH4+, while at pH >9 the reacting species are FeO42– and NH3. At pH 7.5 the reaction occurs according to the following stoichiometry: 8HFeO4– + 3NH4+ + 3H2O →8Fe(OH)3 + 3NO3– + 2OH–. Nitrate is also formed as the predominantly product at higher pHs. Based on the experimental results and DFT calculations, the proposed mechanism involves an oxygen-atom transfer from ferrate(VI) to ammonia to produce hydroxylamine, which is then rapidly oxidized by excess ferrate to nitrate.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 6","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489847","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 solid-state structures of two palladium(II) (6 and 8⋅2CHCl3) and two nickel(II) (12 and 15) complexes could be confirmed by single-crystal X-ray diffraction studies. All the complexes were evaluated as catalysts in the Suzuki-Miyaura cross-coupling reaction. Applying what appeared, from the literature, as the optimized reaction conditions for such complexes, i. e. Cs2CO3 as base and 1,4-dioxane as solvent, the palladium catalysts were found very efficient for the coupling of phenylboronic acid and aryl bromides functionalized with weak and moderate electron donating groups (EDGs) and weak and moderate electron withdrawing groups (EWGs). In contrast, reduced activity was observed for aryl bromides functionalized with strong EDGs and EWGs and no activity for aryl chlorides. Under the same reaction conditions, the nickel catalysts were completely inactive. Applying different and “greener” reaction conditions, i. e. K3PO4 as base and tert-amyl alcohol as solvent, the nickel catalysts efficiently converted various aryl bromides and chlorides with a pool of aryl boronic acids, therefore clearly surpassing their palladium analogues at lower cost, economically and environmentally. Surprisingly, these reaction conditions could also be successfully applied to the palladium complexes, improving their performances (activity towards aryl chlorides) and offering a “greener” alternative to the common conditions.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 6","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202400729","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489883","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}
