Polymorphism in diphenyl ether has been identified during in situ crystallization via single-crystal X-ray diffraction. Only weak inter- and intramolecular C−H···π interactions control the packing of the molecules in both crystal forms monoclinic centrosymmetric (P21/n) in form I and orthorhombic noncentrosymmetric (P212121) in form II.
