Origin of phase relative stability and phase transformation in an S-ibuprofen-nicotinamide cocrystal
{{output}}
The crystal structure of the metastable form of S-ibuprofen-nicotinamide cocrystals, C13H18O2·C6H6N2O, was solved from powder X-ray diffraction. This form was obtained by melting a molar mixture of S-ibuprofen and nicotinamide at 100 °C, and then cooling. Th... ...
