Crystal structure and Hirshfeld surface analysis of 2,5-diimino-8a-methyl-4,9-bis(4-methylphenyl)-7-oxo-6-phenyl-decahydro-2H-3,8-methanopyrano-[3,2-c]pyridine-3,4a-dicarbonitrile N,N-dimethyl-formamide monosolvate

In the title compound, C32H29N5O2·C3H7NO, the bicyclo[3.3.1]nonane ring system adopts a half-chair/twist-boat conformation, with the phenyl rings in equatorial orientations with respect to the piperidine ring. The two oxane rings of the 2-oxabicyclo[2.2.2]octane ring system exhibit a distorted boat conformation. Intermolecular C—H· · ·O and C—H· · ·N hydrogen bonds connect the molecules in the crystal, generating layers extending parallel to (100). These layers are connected by C—H· · ·π interactions. A Hirshfeld surface analysis was performed to quantify the contributions of the different intermolecular interactions, indicating that the most important contributions to the crystal packing are from H· · ·H (52.5%), N· · ·H/H· · ·N (19.2%), C· · ·H/H· · ·C (18.8%) and O· · ·H/H· · ·O (8.3%) interactions. © 2023 International Union of Crystallography.
