Abstract

An analysis of structural features associated with polymorphism in 3-acetylcoumarin has been made in terms of morphology, infrared spectroscopy, crystal structure, powder X-ray diffraction, and differential scanning calorimetric measurements. The appearance of concomitant polymorphe is found to depend on the crystallization temperature in the 1:1 chloroform/hexane solvent system. C-H⋯O and C-H⋯π interactions stabilize one form in a head to head configuration, while only C-H⋯O interactions stabilize the other in a head to tail configuration of the molecules in the crystal lattice.
