The crystal packing is mainly influenced by slipped \u03c0\u2013\u03c0 stacking interactions, along with weak C\u2014H...O interactions involving the sulfonyl oxygen atoms. Hirshfeld surface analysis shows that H...H (46.6%), O...H\/H...O (23.5%), C...H\/H...C (16.0%) and C...C (8.0%) contacts make the major contributions to the crystal packing.\n                  <\/jats:p>","DOI":"10.1107\/s2414314626009272","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T05:41:52Z","timestamp":1788846112000},"update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["5-Cyclopropyl-1-[(4-methylbenzene)sulfonyl]indole-2-carbaldehyde"],"prefix":"10.1107","volume":"11","author":[{"given":"Veeranjaneyulu","family":"Avula","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03gtcxd54","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Keerthana V.K.","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.D.","family":"Yash","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03tjsyq23","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Umamaheshwar S.","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5099-3384","authenticated-orcid":true,"given":"Nagendra","family":"Govindappa","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03gtcxd54","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0953-1196","authenticated-orcid":true,"given":"Jayaraman","family":"Muthukumaran","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03tjsyq23","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2654-5001","authenticated-orcid":true,"given":"Kuppuswamy","family":"Arumugam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Surya Prakash Rao H.","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"bx4042_bb1","unstructured":"Bruker (2016).
