Fingerprint plots of the title compounds; full Hirshfeld surface (left) and delineated into H⋯O, H⋯C, C⋯C, and H⋯H contacts, showing the percentage contributions of the contacts to the total Hirshfeld surface area of the mol­ecules. First row: compound I; second row: compound II; third row: 3-(4-chloro­benzyl­idene)-2-phenyl-2,3-di­hydro-4H-chromen-4-one (Kupcewicz et al., 2013BB23); fourth row: (E)-3-(4-N,N-di­ethyl­amino­benzyl­idene)chroman-4-one (Adamus-Grabicka et al., 2018BB1); fifth row: (E)-3-(4-N,N-di­ethyl­amino­benzyl­idene)-2-phenyl­chroman-4-one (Adamus-Grabicka et al., 2018BB1).
