Abstract

The molecular conformation of the title compound, C17H14ClN3O4 , is stabilized by an intramolecular C-H center dot center dot center dot O contact, forming an S(6) ring motif. In the crystal, the molecules are connected by N - H center dot center dot center dot O hydrogen-bond pairs along the b-axis direction as dimers with R-2(2)(8) and R-2(2)(14) ring motifs and as ribbons formed by intermolecular C-H center dot center dot center dot N hydrogen bonds. There are weak van der Waals interactions between the ribbons. The most important contributions to the surface contacts are from H center dot center dot center dot H (34.9%), O center dot center dot center dot H/H center dot center dot center dot O (19.2%), C center dot center dot center dot H/H center dot center dot center dot C (11.9%), Cl center dot center dot center dot H/H center dot center dot center dot Cl (10.7%) and N center dot center dot center dot H/H center dot center dot center dot N (10.4%) interactions, as concluded from a Hirshfeld surface analysis.
