An intramolecular C\u2014H...Br hydrogen bond between a methine H atom and the Br substituent at the phenyl ring leads to the stabilization of the molecular conformation. Intermolecular C\u2014H...O hydrogen bonds as well as \u03c0\u2013\u03c0 interactions are observed in the crystal. The intermolecular interactions were quantified and analysed using Hirshfeld surface analysis, revealing that H...H interactions contribute most (46.9%) to the crystal packing.\n                  <\/jats:p>","DOI":"10.1107\/s2056989025006413","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T05:55:33Z","timestamp":1753077333000},"page":"723-726","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structure and Hirshfeld surface analysis of 3-[(\n                    <i>E<\/i>\n                    )-2-(2-bromo-4,5-dimethoxyphenyl)ethenyl]-5,5-dimethylcyclohex-2-en-1-one"],"prefix":"10.1107","volume":"81","author":[{"given":"Muruganandham","family":"Rajkumar","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01x24z140","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uthirapathi","family":"Rajapandiyan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01x24z140","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haridoss","family":"Manikandan","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01x24z140","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Velusamy","family":"Rajathi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sivashanmugam","family":"Selvanayagam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2025,7,23]]},"reference":[{"key":"wm5763_bb1","doi-asserted-by":"crossref","first-page":"1555","DOI":"10.1002\/anie.199515551","volume":"34","author":"Bernstein","year":"1995","journal-title":"Angew.
