3-{2-[2-(Diphenylmethylene)hydrazinyl]thiazol-4-yl}-2H-chromen-2-one

Abstract

In the title compound, C25H17N3O2S, the coumarin ring system is essentially planar with a maximum deviation of 0.019 (2) Å. A weak intramolecular C—H...O hydrogen bond stabilizes the molecular structure, so that the coumarin plane is approximately coplanar with the thiazole ring, making a dihedral angle of 2.5 (10)°. The two phenyl rings are nearly perpendicular to each other, with a dihedral angle of 81.44 (12)°. In the crystal structure, the molecules are linked into an infinite chain along the b axis by intermolecular C—H...O hydrogen bonds. Weak C—H...π interactions are observed between the chains.
