The complexes which formed due to the interaction of Ni(II), Zn(II), Cu(II), Gd(III) and Sm(III) with ciprofloxacin were characterized by CHN% analysis, conductivity, FTIR, electronic spectra, fluorescence measurements, and magnetic susceptibility, besides studying the complex–DNA interaction. Meanwhile, the molar conductance values (0.001 mol·L⁻¹ in DMSO) revealed the electrolytic behavior of the complexes and could be designated with the A⁻B⁺ formula. In addition, the geometry of the compounds was confirmed from the electronic transitions as well as the <i>μ</i>_eff values as octahedral for all complexes. The postulated formula could be generally assigned as [M(CIP)_<i>a</i>(CIPH)_<i>b</i>(H₂O)_<i>c</i>](NO₃)(H₂O)_<i>n</i>(C₂H₅OH)_<i>m</i>. Moreover, the interaction between metal complexes and DNA revealed that the Cu complex had the highest binding constant. Nanotechnology was applied to synthesized compounds using silica nanoparticles (SiNPs), which were prepared using a sol–gel process. The silica nanoparticles were chemically functionalized for binding the ligand and its metal complexes; this enables the as-prepared compounds to enhance their features as a drug delivery platform. Meanwhile, the antimicrobial activity was tested for the free complexes and SiNPs composites. Collectively, Sm complex gave the largest zone of inhibition, while the Cu(II)–SiNPs composite showed the strongest potential to reduce the bacterial activity. Furthermore, the fluorescence data of CIPH, ligand–metal mixture and the effect of silica nanoparticles on them were studied.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10953-024-01375-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886379","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}

In the present study, Catalan’s hydrogen bond basicity and acidity parameters, <i>SB</i> and <i>SA</i>, and Gutmann’s acceptor number, <i>AN</i>, a measure of a solvent’s Lewis acidity, are correlated with molecular properties derived from computational chemistry.

After the formation of HDES, the IR absorption peaks of Hexen, Nonen's–NH₂, and Men–OH fused into a wider peak, the ¹H-NMR spectra of Men–OH, shifted to a lower field. Furthermore, a significant redshift approximately 300 cm⁻¹ was detected in the vibrational frequency of the Men–OH functional group when performing density functional theory (DFT) calculations for the HDESs. These results support the development of stronger O–H···N bonds between Hexen/Nonen–NH₂ and Men–OH, and the calculated sum of hydrogen bonding energy was approximately 56 mol·kg^–1, categorizing it as an intermediate-strength hydrogen bond. Both HDESs have ethylenediamine polar heads in their hydrogen bond acceptors, which have chelating characteristics that help them coordinate with transition metal ions. Metal ions such as Cu(II), Co(II), and Ni(II) were successfully extracted from aqueous solutions at a concentration of 10 mmol·L^–1using HDESs. The Cu(II) and Ni(II) extraction efficiencies exceeded 90%, indicating their effectiveness. Notably, even at higher metal ion concentrations (100 mmol·L^–1), the extraction efficiencies of all three metal ions remained consistently below 80%.
