Crystal structure and Hirshfeld surface analysis of isopropyl 4-[2-fluoro-5-(tri-fluoro-meth-yl)phen-yl]-2,6,6-trimethyl-5-oxo-1,4,5,6,7,8-hexa-hydro-quinoline-3-carboxyl-ate.

ABSTRACT

In the title compound, C23H25F4NO3, the 1,4-di-hydro-pyridine ring adopts a distorted boat conformation, while the cyclo-hexene ring is almost showing a half-chair conformation. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the mol-ecules 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 inter-actions, forming a three-dimensional network. In addition, C-H⋯π inter-actions link the mol-ecules into layers parallel to the (100) plane. A Hirshfeld surface analysis was performed to further investigate the inter-molecular inter-actions.
