Based on the results, Rn is considered to interact with F through the van der Waals force, which limits the volatilization of Rn from the solution. NZ and FFNZ achieved ~40% and ~70% removal of Rn, respectively, following 24 h of treatment, indicating a significant impact of F (in FFNZ) toward Rn removal from groundwater. The redundancy analysis revealed a positive correlation between the concentrations of Rn and fluorine (F) in groundwater, indicating that F can support the long-term retention of Rn in groundwater. In this study, we conducted a redundancy analysis (RDA) of Rn in groundwater and performed batch sorption experiments for efficient Rn removal from the groundwater collected from Daejeon using natural zeolite (NZ) and fluorine-functionalized natural zeolite (FFNZ) sorbents. Therefore, studying the chemical factors influencing the content and removal of Rn from groundwater is crucial for the evaluation and mitigation of its radiological risks to public health. Radon (Rn) can easily leak into the environment through groundwater owing to its high water solubility. Concretely, special attention is given to xenon fluorides and xenon oxides, since they exhibit a strong tendency to establish NgBs. Moreover, exploring the Cambridge Structural Database (CSD) and Inorganic Crystal Structure Database (ICSD), it is demonstrated that NgB interactions are crucial in governing the X-ray packing of xenon derivatives. Several theoretical works have described the physical nature of NgB and their interplay with other noncovalent interactions, which are discussed herein. Nevertheless, in this short review, relevant theoretical and experimental investigations on noncovalent interactions involving Xenon are emphasized. For obvious reasons, the works devoted to the study of noncovalent Ng-bonding interactions are significantly less abundant than halogen, chalcogen, pnictogen, and tetrel bonding. They are becoming acting players in essential fields such as crystal engineering, supramolecular chemistry, and catalysis. Investigations dealing with noncovalent interactions involving main group elements (acting as Lewis acids) have rapidly grown in recent years. The IUPAC already recommended systematic nomenclature for the interactions of groups 17 and 16 (halogen and chalcogen bonds, respectively). Noble gas (or aerogen) bond (NgB) can be outlined as the attractive interaction between an electron-rich atom or group of atoms and any element of Group-18 acting as an electron acceptor. To the best of our knowledge this is a first report on utilization of a web-based application employed in a successful design of anion receptors through C-H Further, the fluoro substituted electron deficient aryl base is assisting the anion recognition process by L with its π-hole moiety through anion ![]() Detailed MEP surface analysis show the nitro substitution in the aryl moiety at 2nd and 4th position of each phenyl arms leave the 6th C-H units more acidic which can actively participate in the anion recognition effectively through C-H we have used web-based MolView application software to generate molecular electrostatic potential surface for our imine based, electron deficient aryl backboned tripodal model receptor L. In addition, the MEP surface analysis also play vital role in the designing of effective receptors for anion binding. π interactions in receptor-anion complexes.We have used Molecular Electrostatic Potential (MEP) surface analysis as a web based theoretical tool to visualize and support our experimental finding on existence of C-H The molecular stability of radon di-, tetra-, and hexafluoride obtained through calculations may lead to advances in radon chemistry. Moreover, we provide the vibrational spectra of our predicted radon fluorides as a reference. Coupled-cluster calculations reveal that RnF6 stabilizes with Oh point symmetry, unlike XeF6 with C3v symmetry. ![]() Similar to xenon fluorides, di-, tetra-, and hexafluorides are found to be stabilized. Here, we study the formation of radon molecules using first-principles calculations additionally, possible compositions of radon fluorides are predicted using a crystal structure prediction approach. Nevertheless, because all isotopes of radon are radioactive and the longest radon half-life is only 3.82 days, experiments on radon chemistry have been limited. Radon is a naturally occurring radioactive noble gas, and the formation of radon-fluorine molecules is of significant interest owing to its potential application in future technologies that address environmental radioactivity. However, previous studies have suggested that these gases can form molecules when they combine with other elements with high electron affinity, such as fluorine. Noble gases possess extremely low reactivity because their valence shells are closed.
