A new polymorph of 4,4′-(ethyl-enedi-oxy)dibenzaldehyde

Abstract

The crystal structure of a new crystalline form of 4,4′-(ethyl-enedi- oxy)dibenzaldehyde, C16H14O4, has been determined in the space group Cc using low-temperature X-ray diffraction data. The two phenyl rings have a dihedral angle of 76.03 (6)°, in contrast to their near-coplanarity in the previously reported polymorph. © International Union of Crystallography 2007.
