Crystal structure and Hirshfeld surface analysis of 1-[6-bromo-2-(3-bromophenyl)-1,2,3,4-tetrahydroquinolin-4-yl]pyrrolidin-2-one

Abstract

This study presents the synthesis, characterization and Hirshfeld surface analysis of 1-[6-bromo-2-(3-bromophenyl)-1,2,3,4-tetrahydroquinolin-4-yl]pyrrolidin-2-one, C19H18Br2N2O. In the title compound, the pyrrolidine ring adopts a distorted envelope configuration. In the crystal, molecules are linked by intermolecular N—H...O, C—H...O and C—H...Br hydrogen bonds, forming a three-dimensional network. In addition, pairs of molecules along the c axis are connected by C—H...π interactions. According to a Hirshfeld surface study, H...H (36.9%), Br...H/H...Br (28.2%) and C...H/H...C (24.3%) interactions are the most significant contributors to the crystal packing.
