In the crystal, intermolecular bifurcated C\u2014H...O hydrogen bonds link the molecules into infinite chains along the\n                    <jats:italic>a<\/jats:italic>\n                    -axis direction. The \u03c0\u2013\u03c0 stacking interactions between the benzene rings of adjacent molecules help to consolidate the three-dimensional architecture. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (54.5%), H...C\/C...H (23.7%), H...O\/O...H (10.6%) and C...C (9.8%) interactions.

Evaluation of the electrostatic, dispersion and total energy frameworks indicates that the stabilization largely depends on dispersion energy contributions. Hydrogen bonding, \u03c0\u2013\u03c0 and van der Waals interactions, together with the dispersion energy contributions, are the dominant interactions in the crystal packing.\n                  <\/jats:p>","DOI":"10.1107\/s2056989026000599","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T10:26:40Z","timestamp":1769423200000},"page":"221-226","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":1,"title":["Crystal structure and Hirshfeld surface analysis, crystal voids, interaction energy calculations and energy frameworks of\n                    <i>C<\/i>\n                    -anthracen-9-yl-\n                    <i>N<\/i>\n                    -methyl aldonitrone"],"prefix":"10.1107","volume":"82","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8949-8698","authenticated-orcid":true,"given":"Jamal","family":"Lasri","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02ma4wv74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed M.","family":"Zayed","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02ma4wv74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9094-8393","authenticated-orcid":true,"given":"Yaseen A.","family":"Almehmadi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02ma4wv74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naser E.","family":"Eltayeb","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02ma4wv74","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8602-4382","authenticated-orcid":true,"given":"Tuncer","family":"H\u00f6kelek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8578-7054","authenticated-orcid":true,"given":"Aidan P.","family":"McKay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"vm2323_bb1","doi-asserted-by":"crossref","first-page":"16387","DOI":"10.1039\/c3dt51593a","volume":"42","author":"Banerjee","year":"2013","journal-title":"Dalton Trans."},{"key":"vm2323_bb2","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1016\/j.jlumin.2019.03.026","volume":"211","author":"Barwiolek","year":"2019","journal-title":"J.
