| Abstract | In the title compound, C(24)H(16)Cl(2)N(2)O(3), the chromene ring system is almost planar, with a maximum deviation of 0.042 (1) Å. It makes dihedral angles of 3.72 (6), 73.37 (5) and 12.00 (5)° with the dihydro-pyrazole, benzene and phenyl rings, respectively. An intra-molecular O-H⋯N hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming an infinite chain along the a axis. The crystal packing is further stabilized by a π-π stacking inter-action [centroid-centroid distance = 3.5471 (7) Å] and a Cl⋯Cl short contact [Cl⋯Cl = 3.214 (1) Å]. |
