Abstract
In the title compound, C24H16Cl2N2O3, the chromene ring system is almost planar, with a maximum deviation of 0.042 (1) angstrom. It makes dihedral angles of 3.72 (6), 73.37 (5) and 12.00 (5)degrees with the dihydropyrazole, benzene and phenyl rings, respectively. An intramolecular O-H center dot center dot center dot N hydrogen bond forms an S(6) ring motif. In the crystal, molecules are linked via C-H center dot center dot center dot O interactions, forming an infinite chain along the a axis. The crystal packing is further stabilized by a pi-pi stacking interaction [centroid-centroid distance = 3.5471 (7) angstrom] and a Cl center dot center dot center dot Cl short contact [Cl center dot center dot center dot Cl = 3.214 (1) angstrom].
