Br...Br contacts between polybromide anions generate supramolecular two-dimensional layers propagating along the\n                    <jats:italic>bc<\/jats:italic>\n                    plane. Organic cations are accommodated inside anionic layers and interact with tribromide anions through N\u2014H...Br contacts. The structure is additionally stabilized by weak C\u2014H...Br interactions linking the organic cations and [Br\n                    <jats:sub>3<\/jats:sub>\n                    ]\n                    <jats:sup>\u2212<\/jats:sup>\n                    . Hirshfeld surface analysis and associated fingerprint plots reveal that the main contributions to the crystal packing are provided by Br...H interactions (84.8%), followed by less chemically meaningful H...H (15.2%) contacts. As a novel example of a tribromide salt, the reported compound is of interest toward its potential use in organic synthesis as a regioselective brominating agent, in oxidation chemistry, and in materials processing involving metal dissolution and recovery.\n                  <\/jats:p>","DOI":"10.1107\/s2056989025009065","type":"journal-article","created":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T07:43:34Z","timestamp":1761205414000},"page":"1067-1070","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structure and Hirshfeld surface analysis of 1,4-diazabicyclo[2.2.2]octanediium bis(tribromide)"],"prefix":"10.1107","volume":"81","author":[{"given":"Dmytro A.","family":"Haleliuk","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5321-9856","authenticated-orcid":true,"given":"Laurentiu","family":"Baltag","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dina D.","family":"Naumova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valeriia O.","family":"Zozulia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sofiia V.","family":"Partsevska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2025,10,28]]},"reference":[{"key":"nx2030_bb1","doi-asserted-by":"crossref","first-page":"1127","DOI":"10.1039\/c39850001127","author":"Allwood","year":"1985","journal-title":"J.
