Both 10-(2-hydroxyethyl)acridin-9(10H)-one, C15H13NO2, and 10-(2-chloroethyl)acridin-9(10H)-one, C15H12ClNO, have monoclinic (P21/c) symmetry and supramolecular three-dimensional networks. But the differences in the intermolecular interactions displayed by the hydroxy group and the chlorine substituent lead to stronger intermolecular π-stacking interactions and hydrogen bonding, and hence a significantly higher melting point for the former.
