[eng] In the present work the ability of two modified nucleobases, 1-ethyluracil and
9-ethyladenine, to form multicomponent crystalline compounds such as cocrystals
and/or salts has been addressed.
Grinding methods were explored in a first attempt. Then in order to obtain suitable single
crystals for structure resolution, solvent cocrystallizations were performed. Through the
physico-chemical characterization and the analysis of the molecular arrangements for
the new compounds, the effect of the different coformers on the resulting
interactions/synthons have been studied, which is fundamental in crystal engineering.
