The dihedral angles between these groups are<jats:italic>A<\/jats:italic>\/<jats:italic>B<\/jats:italic>= 57.47\u2005(1),<jats:italic>A<\/jats:italic>\/<jats:italic>C<\/jats:italic>= 18.48\u2005(1) and<jats:italic>B<\/jats:italic>\/<jats:italic>C<\/jats:italic>= 57.97\u2005(1) \u00b0. The ethyl acrylate group at the 2-position is nearly co-planar with the indole unit [3.81\u2005(2)\u00b0], while that at the 7-position is distinctly non-coplanar [52.64\u2005(1)\u00b0]. Intramolecular \u03c0\u2013\u03c0 interactions between the indole unit and benzene ring help to establish the clip-shaped conformation of the molecule. In the crystal, the molecules are assembled into two-dimensional layers<jats:italic>via<\/jats:italic>C\u2014H...O hydrogen bonds, \u03c0\u2013\u03c0 and C\u2014H...\u03c0 interactions. Hirshfeld surface analysis illustrates that the greatest contributions are from H...H (63.2%), C...H\/H...C (15.4%) and O...H\/H...O (14.8%) contacts. The terminal C<jats:sub>2<\/jats:sub>H<jats:sub>5<\/jats:sub>group of one of the ethyl acrylate side chains is disordered over two positions of equal occupancy.<\/jats:p>","DOI":"10.1107\/s2056989021007829","type":"journal-article","created":{"date-parts":[[2021,8,6]],"date-time":"2021-08-06T08:19:55Z","timestamp":1628237995000},"page":"895-898","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structure and Hirshfeld analysis of diethyl (2<i>E<\/i>,2\u2032<i>E<\/i>)-3,3\u2032-[1-(8-phenylisoquinolin-1-yl)-1<i>H<\/i>-indole-2,7-diyl]diacrylate"],"prefix":"10.1107","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5942-505X","authenticated-orcid":true,"given":"Xue-Jun","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2021,8,6]]},"reference":[{"key":"zn2008_bb2","unstructured":"Bruker (2014).
