摘要：

It has been reported previously that the photoreactive beta phase of p-formyl-trans-cinnamic acid represents an exception to the well-established correlation between structural and photochemical properties of crystalline trans-cinnamic acid derivatives. However, it is shown in this paper that the crystal structure reported previously to be the beta phase of p-formyl-trans-cinnamic acid is actually the photostable gamma phase. In a wider context, the work reported here highlights the necessity of carrying out powder diffraction investigations in the determination of structure-property relationships for crystalline solids.
