2-ethylthio-9-methyl-1,4-dihydroacridine-1,4-dione and 9-methyl-2-(4-tolylthio)-1,4-dihydroacridine-1,4-dione.
The title compounds, C16H13NO2S, (I), and C21H15NO2S, (II), have similar molecular structures that differ only in the side groups attached to the S atom. The crystal packing is dominated by pi-pi stacking interactions, involving acridinedione-acridinedione overlap in (I) and both acridinedione-acridinedione and acridinedione-tolyl overlap in (II).
