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.

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.
