Abstract
An X-ray structural investigation (1274 reflections, R = 0.057) has es tablished that 2-(p-tolyl)amino-5,6-benzo-2H-chromene exists in the cr ystalline state as a cyclic 2H-chromene tautomer. This molecule is non planar due to the tetrahedral coordination of the C(1) atom and the re lative rotation of phenyl and benzochromene rings.
