The 4-HO-DET structure exhibits a single tryptammonium cation and a single hydrofumarate anion in the asymmetric unit. The ions are joined together by N\u2014H...O and O\u2014H...O hydrogen bonds in two-dimensional sheets lying in the (001) plane. The 4-AcO-DET structure exhibits a single tryptammonium cation, half of a fumarate dianion and half of a fumaric acid molecule in the asymmetric unit. The ions and molecules are joined together by N\u2014H...O and O\u2014H...O hydrogen bonds in an infinite three-dimensional network.\n                  <\/jats:p>","DOI":"10.1107\/s2056989026009217","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T08:58:00Z","timestamp":1788771480000},"page":"1165-1169","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structures of new psychoactive substances 4-HO-DET and 4-AcO-DET"],"prefix":"10.1107","volume":"82","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-8656-0747","authenticated-orcid":true,"given":"Marilyn","family":"Naeem","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ydmy275","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9489-4919","authenticated-orcid":true,"given":"Christopher","family":"Pauli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caleb","family":"King","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0449-0337","authenticated-orcid":true,"given":"Andrew R.","family":"Chadeayne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6615-1253","authenticated-orcid":true,"given":"James A.","family":"Golen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ydmy275","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2513-4801","authenticated-orcid":true,"given":"David R.","family":"Manke","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04ydmy275","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"vm2336_bb1","unstructured":"Bruker (2025).
