Formation of (a) dimer by two symmetry-independent molecules (black and green) in the asymmetric unit of 5c utilizing C-H···O, C-H···N and C-H···π interactions. (b) Crystal packing for 5c molecules via the association of dimeric motifs (light red) through C-H···O and π···π stacking interactions. (c) Packing arrangement of 5d molecules stabilized via various strong to weak C-H···O (light blue) and C-H···F (light green) dimers. Different-colored carbon atoms indicate different symmetry-independent molecules. Non-interacting hydrogen atoms were removed in the case of 5d to clarify the packing view.
