Crystal structure and Hirshfeld surface analysis of isopropyl 4-[2-fluoro-5-(trifluoromethyl)phenyl]-2,6,6-trimethyl-5-oxo-1,4,5,6,7,8-hexahydro-quinoline-3-carboxylate

In the title compound, C23H25F4NO3, the 1,4-dihydropyridine ring adopts a distorted boat conformation, while the cyclohexene ring is almost showing a half-chair conformation. In the crystal, intermolecular N—H· · ·O hydrogen bonds connect the molecules into chains with graph-set motif C(6) parallel to the a-axis. These chains are linked together by C—H· · ·O and C—H· · ·F interactions, forming a three-dimensional network. In addition, C—H· · ·π interactions link the molecules into layers parallel to the (100) plane. A Hirshfeld surface analysis was performed to further investigate the intermolecular interactions. © 2023 International Union of Crystallography. All rights reserved.
