The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021\u2005(1)\u2005\u00c5 for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to the propynyl group, as indicated by the N\u2014C\u2014C\u2014C torsion angle of 77.9\u2005(1)\u00b0. In the crystal, molecules are linked by C\u2014H...O hydrogen bonds and \u03c0\u2013\u03c0 interactions between benzene rings [intercentroid distance = 3.5630\u2005(10)\u2005\u00c5], forming a three-dimensional structure.<\/jats:p>","DOI":"10.1107\/s1600536814003973","type":"journal-article","created":{"date-parts":[[2014,2,25]],"date-time":"2014-02-25T09:30:15Z","timestamp":1393320615000},"page":"o360-o360","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":1,"title":["1-(Prop-2-ynyl)indoline-2,3-dione"],"prefix":"10.1107","volume":"70","author":[{"given":"Fatima-Zahrae","family":"Qachchachi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fouad","family":"Ouazzani Chahdi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Houria","family":"Misbahi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Bodensteiner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lahcen","family":"El Ammari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2014,2,26]]},"reference":[{"unstructured":"Agilent (2013).
