An extensive temperature-dependent 1H NMR study of TpPh,MeCo(NO3) in a non-interacting, non-polar organic solvent (toluene), from 187 to 357 K is presented. The protons of the TpPh,Me ligand indicate the coordinated nitrate anion is surprisingly dynamic. The complex transitions near 247 K, from a time-average four-coordinate structure at elevated temperature, to three limiting structures in low temperature solution. The low temperature data are consistent with the persistence of a symmetric four-coordinate structure, and two new asymmetric five-coordinate structures. The three species appear in near equimolar amounts at the lowest temperatures, with the five-coordinate species decreasing, and the four-coordinate species increasing, as the temperature is raised. Relaxation data are presented that confirm the NMR assignments, and offer insight into the speciation. An X-ray structure of the title compound is also presented, and used as the starting point for DFT and SCF calculations, which show the nitrate ion need only rotate ~45° about the Co⋅⋅Nnitrate direction to interconvert the trigonal-bipyramid favored by DFT and the square-pyramid.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 9","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202400775","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698752","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}

The crystalline structure of SL-1 was revealed by single crystal X-ray diffraction (SC-XRD) analysis, which demonstrates the existence of two different coordination geometries of cooper nodes. Cu1 center is anchored by two carboxylate groups from two H3pbc ligand and coordinates with three water molecules, while Cu2 center is six-coordinated that results in -CuO6-CuO6-CuO6-CuO6- double helix structure. Remarkably, the robust SL-1 demonstrates excellent acid and base resistance when soaking in aqueous solution with pH value ranging from 4–12. In addition, after a high temperature process (~100 °C), the water molecules linked by carboxylate anchored Cu node would be released, while the crystalline nature was preserved and almost unchanged. As a result, the exposed and unsaturated Lewis acid active sites can effectively catalyze aerobic oxidation of benzyl alcohol to benzaldehyde with yield of 73 % and selectivity of nearly 100 %. We believe the presented strategy by integrating phosphonic groups into building blocks to afford stable MOF structure will guide the design of more practical functionalized MOF materials.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 9","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698804","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 presence of FA, two new 27Al NMR peaks appeared at high magnetic fields, in addition to a peak due to Al(H2O)63+, suggesting the formation of monodentate 1 : 1 (AlFA2+) and 1 : 2 (AlFA2+) complexes. The trends observed in the 27Al NMR analysis of the Al-FA complex was well represented by DFT calculations (i. e., move of the chemical shifts to the high magnetic field side, additivity low of the 27Al NMR chemical shift, and change in electron density of each Al3+ nucleus). The average conditional formation constants of the Al-FA complexes were determined to be log K1=1.17 and log K2=0.91 for the 1 : 1 and 1 : 2 complexes. The formation constant of the acetate complex was also determined to be log K=1.80 (1 : 1 complex). These results strongly suggest that natural monocarboxylic acids produced from the decomposition of organic compounds and certain bacterial activities show potential for the detoxification of Al3+, that is, complex formation with toxic Al species in acidified soil.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 11","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822100","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}
