Crystal structure and Hirshfeld surface analysis of (3aRS,4RS,10SR,10aSR)-2-(3,5-di-methyl-phen-yl)-4-hy-droxy-10-methyl-1-oxo-2,3,3a,4,10,10a-hexa-hydro-1H-[1]benzofuro[2,3-f]iso-indole-10-carb-oxy-lic acid di-methyl-formamide monosolvate.

The mol-ecular conformation of the title compound, C(24)H(23)NO(5)·C(3)H(7)NO, is consolidated by intra-molecular C-H⋯O O-H⋯O hydrogen bonds, forming an S(6) ring motif. In the crystal, the mol-ecules are connected by C-H⋯O hydrogen bonds, forming layers parallel to the (101) plane. Furthermore, the mol-ecules form layers parallel to the (102) plane by C-H⋯π inter-actions. Important inter-molecular inter-actions highlighted by Hirshfeld surface analysis are H⋯H (54.7%), O⋯H/H⋯O (23.0%), and C⋯H/H⋯C (19.9%) contacts.
