| Abstract: | An X-ray structural investigation (1274 reflections,R=0.057) has established that 2-(ptolyl)amino-5, 6-benzo-2H-chromene exists in the crystalline state as a cyclic 2H-chromene tautomer. This molecule is nonplanar due to the tetrahedral coordination of the C(1) atom and the relative rotation of phenyl and benzochromene rings.Translated fromIzvestiya Akademii Nauk.
