3-{2-[2-(Diphenyl-methyl-ene)hydrazin-yl]thia-zol-4-yl}-2H-chromen-2-one.


ABSTRACT: In the title compound, C(25)H(17)N(3)O(2)S, the coumarin ring system is essentially planar with a maximum deviation of 0.019?(2)?Å. A weak intra-molecular C-H?O hydrogen bond stabilizes the mol-ecular structure, so that the coumarin plane is approximately coplanar with the thia-zole 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 mol-ecules are linked into an infinite chain along the b axis by inter-molecular C-H?O hydrogen bonds. Weak C-H?? inter-actions are observed between the chains.
