Crystal structure and Hirshfeld surface analysis of (3Z)-7-methoxy-3-(2-phenylhydrazinylidene)-1-benzofuran-2(3H)-one

Abstract

In the title compound, C15H12N2O3, pairs of molecules are linked into dimers by N—H...O hydrogen bonds, forming an R 2 2(12) ring motif, with the dimers stacked along the a axis. These dimers are connected through π–π stacking interactions between the centroids of the benzene and furan rings of their 2,3-dihydro-1-benzofuran ring systems. Furthermore, there exists a C—H...π interaction that consolidates the crystal packing. A Hirshfeld surface analysis indicates that the most important contacts are H...H (40.7%), O...H/H...O (24.7%), C...H/H...C (16.1%) and C...C (8.8%).
