Owing to the localized permanent charges in the ligand core the cage binds iodide anions in specific regions within the cage through ionic interactions. This allows the selective binding of bromomethanes as secondary guest species within the cage promoted by halogen bonding, which was confirmed by single\u2010crystal X\u2010ray diffraction.<\/jats:p>","DOI":"10.1002\/anie.202215689","type":"journal-article","created":{"date-parts":[[2022,12,14]],"date-time":"2022-12-14T13:29:37Z","timestamp":1671024577000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Charge\u2010Assisted Halogen Bonding in an Ionic Cavity of a Coordination Cage Based on a Copper(I) Iodide Cluster"],"prefix":"10.1002","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2504-8196","authenticated-orcid":false,"given":"Anssi","family":"Peuronen","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Turku  20014 Turku Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9825-8258","authenticated-orcid":false,"given":"Anni I.","family":"Taponen","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Jyvaskyla  P.O.
