Abstract
In the title molecule, C25H28N2O5S, (alternative name ethyl 2-{[7-acetyl-4-cyano-6-hydroxy-8-(4-methoxyphenyl)-1,6-dimethyl-5,6,7,8-tetrahydroisoquinolin-3-yl]sulfanyl}acetate) the 4-methoxyphenyl group is disposed on one side of the bicyclic core and the oxygen atoms of the hydroxyl and acetyl groups are disposed on the other side. In the crystal, a layered structure parallel to the ac plane is generated by O—H...O and C—H...O hydrogen bonds plus C—H...π(ring) interactions.

Abstract
The title mol-ecule, C29H29N3O4S, adopts a conformation with the two phenyl substituents disposed on opposite sides of the mean plane of the iso-quinoline unit. In the crystal, corrugated layers of mol-ecules are formed by N-H⋯O, C-H⋯N and C-H⋯S hydrogen bonds together with C-H⋯π(ring) inter-actions. These layers are connected by C-H⋯O contacts. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (45.2%), C⋯H/H⋯C (20.2%), O⋯H/H⋯O (15.8%) and N⋯H/H⋯N (11.0%) inter-actions.

Akkurt M, Marae IS, Mague JT, Mohamed SK, Bakhite EA, Al-Waleedy SAH. Crystal structure and Hirshfeld surface analysis of 2-{[7-acetyl-8-(4-chloro-phen-yl)-4-cyano-6-hy-droxy-1,6-dimethyl-5,6,7,8-tetra-hydro-isoquinolin-3-yl]sulfan-yl}- N-(4-chloro-phen-yl)acetamide. Acta Crystallogr E Crystallogr Commun 2021; 77:527-531.

Abstract
In the title mol-ecule, C28H25Cl2N3O3S, the heterocyclic portion of the tetra-hydro-iso-quinoline unit is planar while the cyclo-hexene ring adopts a twist-boat conformation. The two 4-chloro-phenyl groups extend away from one side of this unit while the hydroxyl and acetyl groups extend away from the opposite side and form an intra-molecular O-H⋯O hydrogen bond. The crystal packing consists of layers parallel to the bc plane. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (37.3%), Cl⋯H/H⋯Cl (17.6%), O⋯H/H⋯O (11.1%), C⋯H/H⋯C (10.9%) and N⋯H/H⋯N (9.7%) inter-actions.
