Crystal structure and Hirshfeld surface analysis of 3-(4-meth-oxy-phen-yl)-2-[(thio-phen-2-yl)carbon-yl]acrylo-nitrile.

Abstract

In the title com-pound, C15H11NO2S, the intra-molecular C-H⋯O hy-dro-gen-bond inter-action forms an S(6) ring motif. The dihedral angle between the planes of the thio-phene and meth-oxy-phenyl ringss 12.26 (15)°. In the crystal, mol-ecular pairs are joined by C-H⋯N contacts, forming R22(16) motifs lying parallel to the (001) plane. They are connected by C-O⋯π and π-π inter-actions [centroid-to-centroid lengths = 3.9049 (18) and 3.9050 (18) Å], resulting in layers parallel to the (100) plane. These layers are linked by C-H⋯N inter-actions. Hirshfeld surface analysis indicates that H⋯H (35.3%), O⋯H/H⋯O (13.5%), C⋯C (12.5%), N⋯H/H⋯N (11.6%), C⋯H/H⋯C (11.6%) and S⋯H/H⋯S (9.0%) inter-actions make significant contributions.
