The crystal structure of the title compound, 4-(2-phenyldiazenyl)-2-[(phenylimino)methyl]phenol, was determined to be an orthorhombic system, Pna21, with cell parameters a = 18.351(4)Å, b = 17.574(4)Å, c = 4.5721(9)Å, V = 1474.5(5)Å3, Z = 4, at 173 K. It was a polymorphism of the previously reported monoclinic system measured at 293 K. This orthorhombic molecule took a more planar shape than the monoclinic one, and did not exhibit intramolecular hydrogen bonds in the crystal.
